Filtered Low Noise Amplifiers
Amplification and bandpass filtering combined in a single part, rejecting out-of-band interference before it reaches the gain stage. Built for GNSS, AIS, ADS-B, ISM band, and other applications where the signal you want is weak and the spectrum around it isn't quiet.
A simpler, more compact alternative to pairing a standalone amplifier with a separate filter, when your target frequency range is already well defined.
