WR-28 Waveguide Lowpass Filter

SWF-60390350-28-L1 is a Ka band waveguide lowpass filter with a passband frequency from 24 to 60 GHz and a rejection frequency 90 to 140 GHz. Due to the waveguide cut off nature, the low side of the filter has rejection range of DC to 20 GHz. The filter provides a nominal insertion loss of 1.0 dB across its passband and a typical rejection of 50 dB. Since the high end cutoff frequency can be changed by modifying the design, custom designs can be offered under different model numbers.
