WR-28 Waveguide Bandpass Filter

SWF-28312340-28-B1 is a Ka band waveguide bandpass filter with a passband frequency from 22 to 34 GHz and the rejection frequencies of DC to 20 GHz and 37 GHz to 70 GHz, respectively. 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.
