Model SWF-40348360-28-L1 is a WR-28 waveguide lowpass filter with a passband frequency from 26.5 to 40 GHz and a rejection frequency 48 to 90 GHz. Due to the waveguide cut off nature, the low side of the filter has rejection range of DC to 21 GHz. The filter provides a nominal insertion loss of 1.0 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.
