Model OWBP-26004000-28 is a Ka band waveguide bandpass filter with a passband frequency from 26 to 40 GHz and the rejection frequencies of 1 kHz to 18 GHz and 48 to 90 GHz, respectively.
The filter provides a nominal insertion loss of 1.2 dB across its passband and a typical rejection of 60 dB. Since both low and high end cutoff frequencies can be changed by modifying the design, custom designs can be offered under different model numbers.
