Model SWF-28301340-28-B1-D is a Ka band waveguide, dual bandpass filter with passband frequencies from 27.5 to 28.5 GHz and 38.0 GHz to 40.0 GHz and rejection frequencies from DC to 25.5 GHz, 30.5 to 35.5 GHz, and 42 to 49 GHz. The filter is designed for 5G freqeuncy band, 28 GHz and 39 GHz system applications, particularly. The nominal insertion loss of the bandpass filter is 3.0 dB and the typical rejection is 40 dB. Since the passband frequencies can be changed by modifying the design, custom designs can be offered under different model numbers.
