High-Performance ADS-B 1090 MHz LNA with Band-Pass Filter

Optimized for ADS-B aircraft tracking, this Low Noise Amplifier (LNA) uses the proven PGA-103+ amplifier and a dedicated 1090 MHz SAW filter (MP02892) to maximize reception quality. It combines ultra-low noise, selectivity, and robust output headroom, making it ideal for demanding aviation monitoring setups.

Mini-FAQ

  • What frequency is it optimized for? — 1090 MHz, the global ADS-B frequency.
  • Do I need a Bias-T? — Yes. Power is injected via 5 V or 3 V Bias-T. Use an external injector if your SDR doesn’t support Bias-T.
  • Can it handle strong nearby signals? — Yes. High IP3 (>41 dBm) plus the SAW filter reduce overload risk, but extra filtering may help in very dense RF environments.
  • Is the input protected? — Yes. Integrated ESD protection is built in.
  • What gain does it provide? — About 8 dB, tuned for ADS-B monitoring without unnecessary saturation.
