Low Pass Filters

Grooved mirror in miter bend for 168 GHz low pass filter in 63.55 mm corrugated waveguide.

When the electric field is in the plane of the miter bend, the transmitted power is attenuated by about 20 dB over a 1.5 to 1 bandwidth above the cutoff frequency. Low pass filters with staggered cutoff frequencies may be cascaded to provide attenuation over wider bandwidths.
