Model OWBP-1040020000-08 is an F band waveguide highpass filter with a passband frequency of 104 GHz and higher and a rejection frequency from DC to 100 GHz.
The filter provides a nominal insertion loss of 2.5 dB across its passband with a low ripple and a typical rejection of 40 dB. Since the low end cutoff frequency can be changed by modifying the design, custom designs can be offered under different model numbers.
