Bragg Reflection Notch Filters
GA has supplied these filters with fundamental notch frequencies at 82.6 GHz, 84 GHz, 105 GHz, 110 GHz, and 140 GHz.
Bragg reflection notch filters with plastic sheets typically have the following characteristics:
- > 30 dB attenuation over 1% bandwidth or
- > 40 dB attenuation over 2% bandwidth
- ~ 1 dB attenuation away from the notches
- harmonics are also rejected
