FM Notch Filter 88-108MHz for Airband applications

Regular price $21.33


FM notch filters are used to reject strong FM signals. 
A good FM Notch filter will reject FM signals and have low insertion loss for signals outside the band.

This is a 7th order Filter with excellent rejection in the FM band. In the absence of a notch filter, FM signals can saturate the receiver. The filter works up to 3 GHz with minimal out-of-band insertion loss.

This FM notch filter is ideally suited for Airband applications in the 118-136 MHz band. The notch filter has been optimized for minimal insertion loss at frequencies higher than 118 MHz while maintaining excellent rejection specifications in the FM band. The specifications of this filter are comparable to filters on the market that cost at least twice as much.
