U-Band Short Slot Hybrid Coupler

SWZ-45355317-19-4B is a U band, short slot 90 degree hybrid coupler that delivers a 3 dB nominal coupling level and 17 dB typical isolation from 45 to 55 GHz. Across the operation frequency band, the coupler can achieve the magnitude imbalance within ±1 dB, and the phase imbalance within ±3 degrees. The interfaces of the coupler are WR-19 waveguides with UG-383/U-M flanges.
