Model OWBP-81008700-12 is an E band waveguide bandpass filter with a passband frequency of 81 to 87 GHz and rejection frequencies from DC to 78 GHz and 90 to 120 GHz.
The nominal insertion loss of the bandpass filter is 2.0 dB and the typical rejection is 30 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.
