WR-19 Waveguide Lowpass Filter

SWF-90311460-19-L1 is a U band waveguide lowpass filter with a passband frequency from 36 to 90 GHz and a rejection frequency 120 to 200 GHz. Due to the waveguide cut off nature, the low side of the filter has rejection range of DC to 30 GHz. The filter provides a nominal insertion loss of 1.5 dB across its passband and a typical rejection of 60 dB. Since the high end cutoff frequency can be changed by modifying the design, custom designs can be offered under different model numbers.
