Model OWBP-59006100-15 is a V band waveguide bandpass filter with a passband frequency of 59 to 61 GHz and rejection frequencies from DC to 58 GHz and 62 to 78 GHz.
The nominal insertion loss of the bandpass filter is 2.5 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.
