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.

110 GHz notch filter in 63.5 mm corrugated waveguide. Plastic sheets are separated by thin sections of corrugated waveguide, which keep the sheets flat.

110 GHz notch filter in 63.5 mm corrugated waveguide. Plastic sheets are separated by thin sections of corrugated waveguide, which keep the sheets flat.

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

GA has supplied these filters with fundamental notch frequencies at 82.6 GHz, 84 GHz, and 110 GHz.

GA also supplies notch filters in fundamental rectangular waveguide.
