WR-51 Waveguide Lowpass Filter

SWF-22325340-51-L1 is a WR-51 waveguide lowpass filter with a passband frequency from 15 to 22 GHz and a rejection frequency 25 to 40 GHz. Due to the waveguide cut off nature, the low side of the filter has rejection range of DC to 12 GHz. The filter provides a nominal insertion loss of 1.0 dB across its passband and a typical rejection of 40 dB. Since the high end cutoff frequency can be changed by modifying the design, custom designs can be offered under different model numbers.
