Chapter 2 Theory of Operation

2.1 IntroductionThis chapter provides a detailed theory of operation for the radio components. Schematic diagrams for the circuits described in the following paragraphs are located in Figures 4-1 through 4-56.

2.2 Radio Power DistributionA block diagram of the DC power distribution throughout the radio board is shown in Figure 2-1. A 7.5V battery supplies the basic radio power (UNSWB) directly to the electronic on/off control, audio power amplifier, 3.5V regulator, power amplifier automatic level control (ALC), and low battery detect circuit. When the radio on/off/volume control is turned on, the switched SWB+ is applied to the various radio power regulators, antenna switch, accessories 20-pin connector, keypad/option board, and transmit LED. The Vdda signal from the 3.3V Vdda regulator supplies the microprocessor with operating power. The Vdd regulator scheme is listed by band in Table 2-1 on page 2-2. Data is then sent to the controller ASFIC to turn on a DAC which takes over the momentary-on path within 12ms. The SWB+ signal supplies power until the radio is turned off. Jumpers for configuring the Vdda and Vddd regulators are shown in Figure 2-1 and described in Table 2-2 on page 2-2.

The radio turns off when either of the two following conditions occur:

• Radio on/off/volume control is turned off.• Low battery condition is detected.

If a low battery level is detected by the microprocessor through either of the above conditions, the radio personality data is stored to EEPROM prior to turning off.

Theory of Operation: UHF1 Transmitter 2-5

2.4.1 Power Amplifier (PA)The PA consists of two LDMOS devices:

• 9Z67 LDMOS driver IC (U101) and • PRF1507 LDMOS PA (Q110)

The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.

This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the frequency range of 403–470MHz.

The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain would typically be 1300mA while operating in the frequency range of 403–470MHz. The power output can be varied by changing the biasing voltage.

2.4.2 Antenna SwitchThe antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104 and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102) pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna and receiver ports.

2.4.3 Harmonic FilterThe harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter for UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.

2.4.4 Antenna Matching NetworkA matching network which is made up of L116 is used to match the antenna's impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.

2.4.5 Power Control Integrated Circuit (PCIC)The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio. The current to the final stage of the power module is supplied through R101, which provides a voltage proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC) within the PCIC to regulate the output power of the transmitter.

The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the control loop. The reference voltage level is programmable through the SPI line of the PCIC.

There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135) in controlling the transmitter rising and falling time. These are necessary in reducing the power splatter into adjacent channels.

CR105 and its associated components are part of the temperature cut back circuitry. It senses the printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be reduced so as to reduce the transmitter temperature.

2-6 Theory of Operation: UHF1 Receiver

2.4.6 Temperature Cut Back CircuitDiode CR105 and associated components are part of a temperature cutback circuit. This circuit senses the printed circuit board temperature around the transmitter circuits and outputs a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, the transmitter output power decreases to reduce the transmitter temperature.

2.5 UHF1 Receiver

2.5.1 Receiver Front-EndThe RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consists of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes (CR101 and CR102) and a pi network (C106, L104 and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filter comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by applying a control voltage to the varactor diodes(CR301 and CR302) in the filter.

The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter across the band.

The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L306, L307, C313, C317, CR304 and CR305.

Theory of Operation: UHF1 Receiver 2-7

Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single control voltage which is DACRx .

The output of the post-RF amplifier filter which is connected to the passive double balanced mixer consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the RF signal is down-converted to the 44.85 MHz IF signal.

The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and L311. The crystal filter provides the necessary selectivity and intermodulation protection.

2.5.2 Receiver Back-End The output of crystal filter FL301 is matched to the input of first IF amplifier transistor Q302 by L330. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The IF amplifer provides a gain of about 16dB. The amplified first IF signal is then coupled into U301(pin 1) via C360 and L332 which provides the matching for the first IF amplifier and U301.

Within U301, the first IF 44.85 MHz signal mixes with the 44.395 MHz second local oscillator (2nd LO) to produce the second IF signal at 455 kHz. The 2nd LO signal frequency is determined by crystal Y300. The second IF signal (455 kHz) is then filtered by an external ceramic filter FL302 before being amplified by the second IF amplifier within U301. Again, the signal is filtered by a second external ceramic filter FL303 or FL304 depending on the selected channel spacing. FL303 is used for 20/25 kHz channel spacing whereas FL304, for 12.5 kHz channel spacing. The simple circuit consisting of U302, CR312, CR313 and resistors R345, R360, R321 and R324 divert the second IF signal according to the BW_SEL line. The filtered output of the second IF signal is applied to the limiter input pin of U301.

The IF IC (U301) contains a quadrature detector using a ceramic phase-shift element (Y301) to provide audio detection. Internal amplification provides an audio output level around 120mVrms (@60% deviation) from pin 8 of U301. This demodulated audio is fed to the ASFIC_CMP IC (U404) in the controller section.

The IF IC (U301) also performs several other functions. It provides a received signal-strength indicator (RSSI) with a dynamic range of 70 dB. The RSSI is a dc voltage monitored by the microprocessor, and used as a peak indicator during the bench tuning of the receiver front-end varactor filter.


2.5.3 Frequency Generation Circuit

The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer (U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally would require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the relevant schematics for the reference designators.

The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U241.

In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data , clock and chip select lines from the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked.

Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO.

Theory of Operation: UHF1 Synthesizer 2-9

2.6 UHF1 SynthesizerThe Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system. The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides 16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.

The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through .

In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43 .

Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

The TRB line (U241 pin 19) determines which oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.

Theory of Operation: UHF2 Transmitter 2-11

The VCOBIC (U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line. The operation logic is shown in Table 2-5.

In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T302 (refer to UHF (403–470 MHz) Receiver Front End Schematic Diagram on page 4-23).During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through the U201 pin 41.When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off.

It also provides 16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.

The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through .

In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43.

Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V square waves (180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

Figure 2-12. VCO Block DiagramThe VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.

The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.

2-18 Theory of Operation: UHF2 Voltage Controlled Oscillator (VCO)

The operation logic is shown in Table 2-6.

In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T302 (refer to UHF (450–512 MHz) Receiver Front End Schematic Diagram on page 4-49).

During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through the U201 pin 41.

When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off.

Theory of Operation: VHF Transmitter 2-19

2.12 VHF TransmitterThe VHF transmitter consists of the following basic circuits as shown in Figure 2-13.

• Power amplifier • Antenna switch/harmonic filter• Antenna matching network• Power control integrated circuit (PCIC)

2.12.1 Power AmplifierThe power amplifier consists of two devices:

• 9Z67 LDMOS driver IC (U3501) • PRF1507 LDMOS PA (Q3501)




2.12.2 Antenna SwitchThe antenna switch circuit consists of two PIN diodes (D3521 and D3551), a pi network (C3531, L3551 and C3550), and two current limiting resistors (R3571, R3572, R3573 ). In the transmit mode, B+ at PCIC (U3502) pin 23 will go low and turn on Q3561 where a B+ bias is applied to the antenna switch circuit to bias the diodes "on". The shunt diode (D3551) shorts out the receiver port, and the pi network, which operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna and receiver ports.

2-20 Theory of Operation: VHF Transmitter

2.12.3 Harmonic FilterThe harmonic filter consists of C3532 to C3536, L3531 and L3532. This network forms a low-pass filter to attenuate harmonic energy of the transmitter to specifications level. The harmonic filter insertion loss should be less than 1.2dB.

2.12.4 Antenna Matching NetworkA matching network which is made up of L3538 and C3537 is used to match the antenna's impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.

2.12.5 Power Control Integrated Circuit (PCIC)The transmitter uses the Power Control IC (PCIC), U3502 to control the power output of the radio by maintaining the radio current drain. The current to the final stage of the power module is supplied through R3519 (0.1ohms), which provides a voltage proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC) within the PCIC to keep the whole loop stable. The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the control loop. The voltage level is controlled by the microprocessor through the data line of the PCIC.There are resistors and integrators within the PCIC, and external capacitors (C3562, C3563 and C3565) in controlling the transmitter rising and falling time. These are necessary in reducing the power splatter into adjacent channels.

U3503 and its associated circuitry acts as a temperature cut back circuitry. This circuitry provides the necessary voltage to the PCIC to cut the transmitter power when the radio temperature gets too high.

Theory of Operation: VHF Receiver 2-21

2.13 VHF Receiver

2.13.1 Receiver Front-EndThe RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consists of L3531, L3532, C3532 to C3563. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes(D3521 and D3551) and a pi network (C3531, L3551 and C3550).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filter comprises of L3301, L3303, C3301 to C3304 and D3301. The bandpass filter is tuned by applying a control voltage to the varactor diode (D3301) in the filter.


The output of the bandpass filter is coupled to the RF amplifier transistor Q3302 via C3306. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L3305, L3306, C3311 to C3314 and D3302.


The output of the post-RF amplifier filter is connected to the passive double balanced mixer which consists of T3301, T3302 and CR3301. Matching of the filter to the mixer is provided by C3317, C3318 and L3308. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using high side injection, the RF signal is down-converted to the 44.85 MHz IF signal.

2-22 Theory of Operation: VHF Receiver

The IF signal coming out of the mixer is transfered to the crystal filter (Y3200) through a resistor pad (R3321 – R3323) and a diplexer (C3320 and L3309). Matching to the input of the crystal filter is provided by C3201 and L3200. The crystal filter provides the necessary selectivity and intermodulation protection.

2.13.2 Receiver Back-EndThe output of crystal filter Y3200 is matched to the input of IF amplifier transistor Q3200 by L3203. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The IF amplifier Q3200 is actively biased by a collector base feedback provided by R3202 and R3203. The gain controlled IF amplifer provides a maximum gain of about 16dB. A dual hot carrier diode (CR3201) limits the filter output voltage swing to reduce overdrive effects at RF levels above -27dBm. The amplified IF signal is then coupled into U3220 (pin 1) via L3202, C3207, and C3200 which provides the matching for the IF amplifier and U3220.

The IF signal applied to pin 1 of U3220 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at pin 7 of U3220.

Within U3220, the first IF 44.85 MHz signal mixes with the 44.395 MHz second local oscillator (2nd LO) to produce the second IF signal at 455 kHz. The 2nd LO signal frequency is determined by crystal Y3201. The second IF signal (455 kHz) is then filtered by an external ceramic filter Y3205 before being amplified by the second IF amplifier within U3220. Again, the signal is filtered by a second external ceramic filter Y3203 or Y3204 depending on the selected channel spacing. Y3203 is used for 20/25 kHz channel spacing whereas Y3204, for 12.5 kHz channel spacing. The simple circuit consisting of U3221, CR3202, CR3203 and resistors R3209, R3212, R3211 and R3205 divert the second IF signal according to the BW_SEL line. The filtered output of the second IF signal is applied to the limiter input pin of U3220 (Pin 14).



2.13.3 Automatic Gain Control (AGC)The front end automatic gain control circuit provides automatic reduction of gain, of the front end RF amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is achieved by drawing some of the output power from the RF amplifier output. At high radio frequencies, capacitor C3327 provides the low impedance path to ground for this purpose. CR3302 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistor Q3301 provides this current.

Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q3301 to saturation i.e. turned on. RSSI is produced by U3220 and is proportional to the gain of the RF amplifier and the input power to the radio.

Resistors R3304 and R3305 are voltage dividers designed to turn on Q3301 at certain RSSI levels. In order to turn on Q3301 the voltage across R3305 must be greater or equal to the voltage across R3324, plus the base-emitter voltage (Vbe) present at Q3301. Capacitor C3209 is used to dampen any instability while the AGC is turning on. The current flowing into the collector of Q3301, a high current gain NPN transistor, will be drawn through the PIN diode to turn it on. Maximum current flowing through the PIN is limited by the resistors R3316, R3313, R3306 and R3324. C3326 is a feedback capacitor used to provide some stability to this high gain stage.

Theory of Operation: VHF Synthesizer 2-23






2.14 VHF SynthesizerThe Fractional-N Synthesizer uses a 16.8MHz crystal (Y3761) to provide a reference for the system. The LVFractN IC (U3701) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C3761, C3762, C3763, R3761 and D3761 , they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides 16.8MHz at pin 19 of U3701 to be used by ASFIC and LVZIF.

The loop filter which consist of C3721, C3722, R3721, R3722 and R3723 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through .

In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U3701 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43 .

Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C3701 to C3704 and triple diodes D3701, D3702. Two 3.3V square waves (180 deg out of phase) are first multiplied by four and then shifted, along with regulated 5V, to build up 13.5V at pin 47 of U3701.

2-26 Theory of Operation: Voltage Control Oscillator (VCO)

The RF section of the VCOBIC(U3801) is operated at 4.54 V (VSF), while the control section of the VCOBIC and Fractional-N synthesizer (U3701) is operated at 3.3V. The operation logic is shown in Table 2-7.

In the receive mode, U3801 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U3801. The RF signal at U3801 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T3302.

During the transmit condition, when PTT is depressed, 3.2 volts is applied to U3801 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U3801. The RF signal at U3801 pin 10 is injected into the input of the PA module (U3501 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through U3701 pin 41.

When a high impedance is applied to U3801 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off.

2.16 Low Band TransmitterThe low band transmitter consists of the following basic circuits as shown in Figure 2-18.


Figure 2-18. Low Band Transmitter Block Diagram


• PA driver, U101.• PA final stage, Q100.

The LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.3V. The amplifier is capable of supplying an output power of 0.3W (pins 6 and 7) with an input signal of 2mW at (pin16). The current drain is typically 120mA while operating in the frequency range of 29.7 –50 MHz. The power output of this stage is varied by the power control loop which controls the voltage on pin 1.

The LDMOS PA is capable of supplying an output power of 8W with an input signal of 0.3W. The current drain is typically 2000 mA while operating in the frequency range of 29.7– 50 MHz. The final stage gate is bias by a voltage from PCIC, pin 24. This voltage is the output of a programmable DAC inside the PCIC and the output is adjustable with the radio tuner.

2-28 Theory of Operation: Low Band Receiver

2.16.2 Antenna SwitchThe antenna switch circuit consists of two pin diodes (D100 and D101), a RF network (C147 and L103), and a DC feed network (L104, C144, and current limiting resistor R101). In the transmit mode, PCIC (U102) pin 32 goes high supplying current via the feed network to bias the diodes “on”. The shunt diode (D101) shorts out the receiver port and L103 is connected from the RF path to ground. L103 and the input capacitance of the lowpass filter form a parallel resonant circuit, effectively disconnecting the receiver port from the antenna while not loading the transmit path. In the receive mode, pin 32 goes low and the diodes are off. D100 looks like a high impedance effectively disconnecting the transmitter from the antenna while L103 and C147 form a series resonant circuit effectively connect the receiver to the antenna.

2.16.3 Harmonic FilterThe harmonic filter consists of components C103, C106, C103, C107,C110, C111, C114, C115 and inductors L100, L101, and L102 which are a part of the SH100 assembly. The harmonic filter for lowband is pole zero design. This feature gives greater attenuation in low frequencies where the harmonic energy of the transmitter is the greatest and less attenuation in high frequencies where there is less harmonic energy. The harmonic filter insertion loss is typically less than 0.8 dB.

2.16.4 Antenna Matching TransformerThe antenna matching transformer (T100) matches the antenna impedance with the harmonic filter to optimize the performance of the transmitter and receiver.

2.16.5 Power Control Integrated Circuit (PCIC)The transmitter uses the PCIC (U102) to regulate the power output of the radio. To accomplish this, the voltage across R102 is sensed. This voltage drop is directly proportional to the current drawn in the final stage of the transmitter. This voltage is compared to a programmable reference inside the PCIC and the voltage on PCIC pin 4 adjusted. Pin 4 connects to the PA driver IC (U101) pin 1 via resistor R100 and varies RF output power of the driver. This controls the current drain of the final stage and sets the output power.

2.16.6 Temperature Cut Back CircuitTemperature sensor VR101 and associated components are part of a temperature cut back circuit. This circuit senses the printed circuit board temperature around the transmitter circuits and outputs a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, the transmitter output power decreases to reduce the transmitter temperature.

2.16.7 Electrostatic Discharge (ESD) Protection CircuitThe LDMOS PA device (Q100) is very sensitive to static discharge. To protect the device from ESD, a protection circuit consisting of single high-speed Schottky Diode (D104) is connected from the Antenna Nut (J102) to ground. This diode effectively shorts ESD energy to ground, but looks like an open circuit to normal RF energy. The diode turns on when the voltage at the antenna nut exceeds 150V.

2.17 Low Band ReceiverThe low band receiver consists of a front end, back end, and automatic gain control circuits. A block diagram of the receiver is shown in Figure 2-19 on page 2-29. Detailed descriptions of these stages are contained in the paragraphs that follow.

Theory of Operation: Low Band Receiver 2-29

Figure 2-19. Low Band Receiver Block Diagram

2.17.1 Receiver Front-EndThe RF signal received by the antenna is routed through the transmitter lowpass filter and antenna switch. These circuits are described in the transmitter section.The signal next passes through a highpass filter consisting of L501, L502, C538, C533 and C504. This filter serves to reject below band signals and has a 3 dB corner frequency of 27 MHz.

The output of the highpass filter is connected to an RF amp consisting of Q509 and associated biasing components. This is a BJT amplifier powered off 5 volts and has 13 dB of gain. The amplifier drives a lowpass filter consisting of L503, L504 L507, C534, C535, C536, C537 and C515. This filter is a pole zero design that filters off harmonic components from the RF amp. The 3 dB corner of this filter is at 56 MHz.

The output of the lowpass filter is connected to the passive double balanced mixer consisting of components T501, T502, and D501. After mixing with the first local oscillator up-converted to a 109.65 MHz IF signal.

The IF signal coming out of the mixer is transferred to the crystal filter (FL301) through a resistor pad (R507, R508 and R509) and a diplexer (C516 and L508). Matching to the input of the crystal filter is provided by L301, L302, C301 and C302. The 3 pole crystal filter provides the necessary selectivity and intermodulation protection.

2-30 Theory of Operation: Low Band Receiver

2.17.2 Receiver Back-End The output of crystal filter FL301 is connected to the input of IF amplifier transistor U301. Components L303 and C348 and R301 form the termination for the crystal filter and the signal is coupled to one gate of U301 by C303. The IF amplifier is a dual gate MOSFET powered off of the 5 volt supply. The first gate receives the IF signal as indicated previously. The second gate receives a DC voltage from U302 which serves as an AGC control signal. This signal reduces the gain of the IF amplifier to prevent overload of the IF IC, U303. The gain can be varied from a maximum of 13 dB to an attenuation of 55 dB. The output IF signal from U301 is coupled into U303 (pin 3) via C306, R304 and L304 which provides matching for the IF amplifier and U303.

The IF signal applied to pin 3 of U303 is amplified, down-converted, filtered, and demodulated, to produce recovered audio at pin 27 of U303. This IF IC is electronically programmable, and the amount of filtering, which is dependent on the radio channel spacing, is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in IF IC U303.

The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U303 so that it is very close to the first IF frequency. The IF IC (U303) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC.

In the absence of an IF signal, the VCO searches for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO locks onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q301. The VCO has a varactor diode, CR301, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of components C308, C309, and R310.

The IF IC (U303) also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the back end.

The demodulated signal on pin 27 of U303 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification.

2.17.3 Automatic Gain Control (AGC)The automatic gain control circuit provides automatic reduction of gain to prevent overloading of backend circuits. This is achieved by lowering the voltage on one gate of U301 which will reduce the drain current in that part and lower its gain.

The Radio Signal Strength Indicator (RSS I) voltage signal for the IF IC (U303) is used to drive the AGC processing circuitry consisting of R306, R307, R308, R309 C307 and U302. As the received signal gets stronger, the RSSI line will rise. When the RSSI line passes a certain threshold, the voltage at the output of U302 will begin to drop. This voltage is connected to one gate of IF amplifier U301 through resistor R305. As this voltage decreases, it will lower the drain current in U301 and reduce the gain of the stage. This will limit the power incident on the IF IC, U303.

2.17.4 Frequency Generation CircuitThe frequency generation circuit, shown in Figure 2-20 on page 2-31, is composed of Low Voltage Fractional-N (LV FracN) synthesizer U205 and discrete RX VCO, TX VCO, and buffers as well as other supporting circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the schematic for the reference designators.

Theory of Operation: Synthesizer 2-31

The synthesizer is powered by regulated 5V and 3.3V. The 5 volt signal to the synthesizer as well as the rest of the radio is provided by U204. The 3.3 v signal is provided by U200 in the controller. The 5V signal goes to pins 13 and 30 while the 3.3V signal goes to pins 5, 20, 34 and 36 of U201. The synthesizer in turn generates a superfiltered 4.3V which powers the VCOs and buffers.

In addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data, clock and chip select lines (pins 7, 8 and 9) from the microprocessor, U409. A 3.3V dc signal from pin 4 indicates to the microprocessor that the synthesizer is locked.

Transmit modulation from the ASFIC is supplied to pin10 of U205. Internally the audio is digitized by the LV FracN IC and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out at pin 41 to the VCO.

Figure 2-20. Low Band Frequency Generation Unit Block Diagram

2.18 SynthesizerThe Low Voltage Fractional-N (LV FracN) synthesizer, shown in Figure 2-21 on page 2-32, uses a 17.0 MHz crystal (Y201) to provide a reference for the system. Along with being used in the LV FracN synthesizer, the 17.0 MHz signal is provided at pin 19 of U205 for use by the ASFIC and LVZIF.

The LV FracN IC (U205) further divides this by 8 internally to give 2.125 MHz to be used as the reference frequency in the frequency synthesis. While UHF and VHF can use other references, (divide by 7 or divide by 7/8), only the divide by 8 function is valid for lowband.

The internal oscillator device in the LV FracN IC together with C236, C237, C242, R219, CR211and Y201 comprise the reference oscillator. This oscillator is temperature compensated is capable of 2.5 ppm stability over temperatures of -30° to 85°C. There is temperature compensation information that is unique to each crystal contained on Y201 that is programmed into the radio when built.

The loop filter consists of components C256, C257, C259, R224, R225 and R228. This circuit provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through.

To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U205 to put the synthesizer within lock range. The required frequency is then locked by normal mode charge pump at pin 43.

2-32 Theory of Operation: Voltage Control Oscillators (VCO)

Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier made up of C247, C283, C284, C285, C286, and triple diodes D210 and D211. This circuit provides 13.3V at U205, pin 47.

Figure 2-21. Low Band Synthesizer Block Diagram

2.19 Voltage Control Oscillators (VCO)2.19.1 Receive VCO

The receive VCO is a Colpitts type design and using two active devices in parallel, Q202 and Q204. The oscillator is powered off of the 4.3 volt super filter supply when the AUX3 line goes low. The oscillator operates from 139 to 152 MHz for range 1 and 145 to 160 MHz for range 2. The frequency is tuned by varactor diodes CR201 and CR202.

2.19.2 Transmit VCOThe transmit VCO is a Hartley-type design with active devices Q203. The oscillator is powered off of the 4.3 volt super filter supply when the AUX2 line goes low. The oscillator operates from 29.7 to 42 MHz for Range 1 and 35 to 50 MHz for Range 2. The frequency is tuned by varactor diodes in U203. Note that the values of the inductive tap, L208 and L209, and the capacitor C215 which couples the varactor to the oscillator tank vary between the ranges.

2.19.3 BufferBoth the receive and transmit VCO are fed to a buffer amplifier Q201. This is a BJT amplifier that boosts the signal levels to +4 dBm and provides reverse isolation to the oscillators. The amplifier is powered off the 4.3 volt super filter supply and the feed network is combined with the transmit filter.

2.19.4 Diplexer/Output FiltersThe output of the buffer drives a pair of parallel filters forming a diplexer. One filter is a lowpass filter in the TX pass that passes 29.7–50 MHz signals for the transmitter into the power amplifier while rejecting the receive LO injection signals at 139–160 MHz. This filter is comprised of L204, L211, L212, C230 and C231.

The other filter is a highpass filter which passes 139 –160 MHz signals for the receive LO into the mixer while rejecting the transmit injection signals at 29.7–50 MHz. This filter is comprised of C228, C229, C235 and L215.

2.19.5 Prescalar FeedbackThe prescalar input signal for receive and transmit is tapped off of the outputs of each filter by resistors R234 and R238. This signal is routed to the buffer amplifier consisting of components C287, Q288, R287, R288, and R289. The output of this buffer feeds U205, pin 32. After frequency comparison in the synthesizer, current is transferred in the loop filter and a control voltage is generated at the output of the loop filter to adjust the frequency of the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.

Chapter 3 Maintenance

3.1 IntroductionThis chapter of the manual describes:

• Preventive maintenance• Safe handling of CMOS devices• Repair procedures and techniques

3.2 Preventive MaintenanceThe radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended.

3.3 InspectionCheck that the external surfaces of the radio are clean, and that all external controls and switches are functional. It is not recommended to inspect the interior electronic circuitry.

3.3.1 CleaningThe following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external and internal surfaces of the radio. External surfaces include the front cover, housing assembly, and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime.

NOTE: Internal surfaces should be cleaned only when the radio is disassembled for servicing or repair.

The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit boards and their components is isopropyl alcohol (100% by volume).

1. Cleaning External Plastic SurfacesThe detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.

2. Cleaning Internal Circuit Boards and ComponentsIsopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away from the inside of the radio. Make sure that controls or tunable components are not soaked with alcohol. Do not use high-pressure air to hasten the drying process since this could cause the liquid to collect in unwanted places. Upon completion of the cleaning process, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or back cover.

CAUTION: The effects of certain chemicals and their vapors can have harmful results on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.!

3-2 Maintenance: Safe Handling of CMOS and LDMOS

NOTE: Always use a fresh supply of alcohol and a clean container to prevent contamination by dissolved material (from previous usage).

3.4 Safe Handling of CMOS and LDMOSComplementary metal-oxide semiconductor (CMOS) and lateral diffusion metal oxide semiconductor (LDMOS) devices are used in this family of radios. Their characteristics make them susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair.

Handling precautions are mandatory for the circuits and are especially important in low humidity conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS CAUTION paragraph in the Disassembly and Reassembly section of the basic manual (See Chapter 3).

3.5 General Repair Procedures and Techniques• Parts Replacement and Substitution

When damaged parts are replaced, identical parts should be used. If the identical replacement component is not locally available, check the parts list for the proper Motorola part number and order the component from the nearest Motorola Communications parts center listed in the “Piece Parts” section of this manual (See Chapter 1).

• Rigid Circuit BoardsThe family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not accessible, some special considerations are required when soldering and unsoldering components. The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.

When soldering near the 20-pin and 40-pin connectors:- Avoid accidentally getting solder in the connector.- Be careful not to form solder bridges between the connector pins.- Closely examine your work for shorts due to solder bridges.

• Flexible CircuitsThe flexible circuits are made from a different material than the rigid boards and different techniques must be used when soldering. Excessive prolonged heat on the flexible circuit can damage the material. Avoid excessive heat and excessive bending.

For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600–700 degree tip, and use small diameter solder such as ST-633. The smaller size solder will melt faster and require less heat to be applied to the circuit.

To replace a component on a flexible circuit: 1. Grasp the edge of the flexible circuit with seizers (hemostats) near the part to be removed. 2. Pull gently.3. Apply the tip of the soldering iron to the component connections while pulling with the seizers.

Do not attempt to puddle out components. Prolonged application of heat may damage the flexible circuit.

Maintenance: General Repair Procedures and Techniques 3-3

• Chip ComponentsUse either the RLN-4062 Hot-Air Repair Station or the Motorola 0180381B45 Repair Station for chip component replacement. When using the 0180381B45 Repair Station, select the TJ-65 mini-thermojet hand piece. On either unit, adjust the temperature control to 700 degrees F. (370 degrees C), and adjust the airflow to a minimum setting. Airflow can vary due to component density.

To remove a chip component:1. Use a hot-air hand piece and position the nozzle of the hand piece approximately 1/8”

(0.3 cm) above the component to be removed.2. Begin applying the hot air. Once the solder reflows, remove the component using a pair of

tweezers. 3. Using a solder wick and a soldering iron or a power desoldering station, remove the excess

solder from the pads.

To replace a chip component using a soldering iron:1. Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder

pads. 2. Using a pair of tweezers, position the new chip component in place while heating the fresh

solder. 3. Once solder wicks onto the new component, remove the heat from the solder. 4. Heat the remaining pad with the soldering iron and apply solder until it wicks to the

component. If necessary, touch up the first side. All solder joints should be smooth and shiny.

To replace a chip component using hot air:1. Use the hot-air hand piece and reflow the solder on the solder pads to smooth it. 2. Apply a drop of solder paste flux to each pad. 3. Using a pair of tweezers, position the new component in place. 4. Position the hot-air hand piece approximately 1/8” (0.3 cm) above the component and begin

applying heat. 5. Once the solder wicks to the component, remove the heat and inspect the repair. All joints

should be smooth and shiny.

• ShieldsRemoving and replacing shields will be done with the R-1070 station with the temperature control set to approximately 415°F (215°C) [445°F (230°C) maximum].

To remove the shield: 1. Place the circuit board in the R-1070’s holder. 2. Select the proper heat focus head and attach it to the heater chimney. 3. Add solder paste flux around the base of the shield. 4. Position the shield under the heat-focus head. 5. Lower the vacuum tip and attach it to the shield by turning on the vacuum pump. 6. Lower the focus head until it is approximately 1/8” (0.3 cm) above the shield. 7. Turn on the heater and wait until the shield lifts off the circuit board. 8. Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off the

vacuum pump. 9. Remove the circuit board from the R-1070’s circuit board holder.

3-4 Maintenance: Recommended Test Tools

To replace the shield: 1. Add solder to the shield if necessary, using a micro-tipped soldering iron. 2. Next, rub the soldering iron tip along the edge of the shield to smooth out any excess solder.

Use solder wick and a soldering iron to remove excess solder from the solder pads on the circuit board.

3. Place the circuit board back in the R1070’s circuit board holder. 4. Place the shield on the circuit board using a pair of tweezers. 5. Position the heat-focus head over the shield and lower it to approximately 1/8” (0.3 cm) above

the shield.6. Turn on the heater and wait for the solder to reflow.7. Once complete, turn off the heat, raise the heat-focus head and wait approximately one

minute for the part to cool. 8. Remove the circuit board and inspect the repair. No cleaning should be necessary.

Maintenance: Replacing the Circuit Board Fuse 3-5

3.7 Replacing the Circuit Board FuseIn cases where the radio fails to turn on when power is applied, the circuit board fuse should always be checked as a probable cause of the failure. The locations of the fuse for both the UHF and VHF boards are shown in Figure 3-1 on page 3-6. The radio must be disassembled to replace the fuses as described in the Basic Service Manual (see section 1.3 on page 1-2), then the circuit board separated from the radio chassis as described in the paragraphs that follow.

Low Band Board

Maintenance: Removing and Reinstalling the Circuit Board 3-7

3.8 Removing and Reinstalling the Circuit Board Both the UHF and VHF circuit boards are removed from the radio chassis in the following manner:

1. Refer to the Basic Service Manual (see Table 1-1, “Related Documents,” on page 1-2) for radio disassembly, then use a Torx driver and a T-6 bit to remove the four Torx screws shown in Figure 3-2.

2. Lift the circuit board out of the radio chassis, then remove and discard the thermal pad located between the circuit board and chassis.

3. After repairs, replace the thermal pad (Motorola P/N 7580556Z01) then reinstall the circuit board into the radio chassis.

4. Reinstall and tighten the four Torx screws to secure the circuit board to the chassis.5. Refer to the Basic Service Manual to reassemble the radio.

Figure 3-2. Circuit Board Removal and Reinstallation

3.9 Power Up Self-Test Error CodesTurning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM hardware and EEPROM checksum. If these checks are successful, the radio generates two high-pitched self-test pass tones. If the self-test is not successful, one low-pitched tone is heard. Radios with displays are able to display the error codes. The displayed error codes and related corrections are as follows:

Table 3-2. Power Up Self-Test Error Codes

If the error code displayed is ...

Then, there is a ... To correct the problem ...

“RAM TST ERROR” RAM test failure. retest the radio by turning it off and turning it on again. If message reoccurs, replace RAM (U405).

“ROM CS ERROR” wrong ROM checksum. replace ROM (U406).

“EEPRM HW ERROR” codeplug structure mismatch or non existence of codeplug.

reprogram codeplug with correct version and retest radio. If message reoccurs, replace EEPROM (U407).

“EEPRM CS ERROR” wrong codeplug checksum.

reprogram codeplug.

Chapter 4 Schematic Diagrams, Overlays, and Parts Lists

4.1 IntroductionThis chapter provides schematic diagrams, overlays, and parts lists for the radio circuit boards and interface connections.

4.1.1 Notes For All Schematics and Circuit Boards* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.

1. Unless otherwise stated, resistances are in Ohms (k = 1000), and capacitances are in picofarads (pF) or microfarads (µF).

2. DC voltages are measured from point indicated to chassis ground using a Motorola DC multimeter or equivalent. Transmitter measurements should be made with a 1.2 µH choke in series with the voltage probe to prevent circuit loading.

3. Reference Designators are assigned in the following manner:- 100 Series = Transmitter- 200 Series = Frequency Generation- 300 Series = Receiver- 400/500 Series = Controller and Low-Band Receiver Front End- 600 Series = Keypad Board

4. Interconnect Tie Point Legend:- UNSWB+ = Unswitched Battery Voltage (7.5 V)- SWB+ = Switched Battery Voltage (7.5 V)- R5 = Receiver Five Volts- CLK = Clock- Vdda = Regulated 3.3 Volts (for analog)- Vddd = Regulated 3.3 Volts (for digital)- CSX = Chip Select Line (not for LVZIF)- SYN = Synthesizer- DACRX = Digital to Analog Voltage (For Receiver Front End Filter)- VSF = Voltage Super Filtered (5 V)- VR = Voltage Regulator
