SWZ-11412417-08-4B is is a F band, short slot 90 degree hybrid coupler that delivers a 3 dB nominal coupling level and 20 dB typical isolation from 110 to 120 GHz. Across the operation frequency band, the coupler can achieve the magnitude imbalance within ±1.5 dB, and the phase imbalance within ±5 degrees. The interfaces of the coupler are WR-08 waveguides with UG-387/U-M anti-cocking flanges.
