Filtered Preamps
These are small filters with a low noise amplifier (LNA) designed to go between a software defined radio receiver and an antenna. Using a SAW or Ceramic bandpass filter and a LNA, they stop out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter in these designs.
