Model OWBP-1250015000-06 is a D band waveguide bandpass filter with a passband frequency of 125 to 150 GHz and rejection frequencies from DC to 100 GHz and 163 to 250 GHz.
The nominal insertion loss of the bandpass filter is 4.5 dB and the typical rejection is 40 dB. Since both low end and high end cut off frequencies can be selected by modifying the design, custom designs are available under different model numbers.
