Baluns vs Amplifiers Balun Amplifiers

Size Large size (mostly ≥ 15mm2) Small size (LMH5401: 6.25mm2)

DC coupled Not suitable for DC coupled application Suitable for DC coupled applications

Frequency response Not suitable for wide bandwidth: Large insertion loss and

varies with frequency

Suitable for wide bandwidth: Minimal insertion loss and almost

constant across frequency

Power gain No power gain - Impedance matching and voltage/current gain are dependent

Supports power gain - Impedance matching and gain are independent

Buffering No buffering - Requirement on previous stage to drive filter and ADC input

load

- No reverse isolation

Buffered - Previous stage is isolated from filter and ADC input load

- Reverse isolation: Avoids ADC switching components going back to

previous stages (ex: antenna)

Distortion Worse distortion due to phase unbalance Better distortion with wideband amplifiers

Noise Less noise (dependent on insertion loss) Noise must match application requirement (LMH5401 9.6dB NF)

Temperature range Limited temp range (ex: -20 to 85C)

Large gain variation across temperature

Wide temp range (ex: -40 to 125C for LMH5401-SP)

Small gain variation across temperature

Reliability Less reliable due to mechanical construction (ex: vibration

during flight)

Reliable due to monolithic implementation

Page 18: Texas Instruments Space Products Roadmap

• Unprecedented usable bandwidth and application flexibility DC to 2GHz.

• Excellent linearity performance through 1GHz

• Supports DC coupled operation, with either single or split supply

operation.

• Easy single-ended in to differential out conversion without external

baluns.

• Low power (280 mW on 5V supply) makes it attractive for a variety of

wide band, high dynamic range applications where power and board

space savings are desirable.
