3-Port Directional Coupler

SWD-3040H-22-SB is a Q band, three-port waveguide directional coupler that delivers a 30 dB nominal coupling level and 35 dB minimum directivity across the full waveguide band from 33 to 50 GHz. The three-port coupler uses a traditional multi-hole and split block design to achieve a flat coupling level, high directivity, and low insertion loss. The interfaces of the coupler are WR-22 waveguides with UG-383/U anti-cocking flanges. Other coupling levels are available under different model numbers.
