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
• 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.
