4-Port Bi-directional Directional Coupler

SWD-0340H-22-BB is a Q band, four-port waveguide bi-directional coupler that delivers a 3 dB nominal coupling level and 35 dB minimum directivity across the full waveguide band from 33 to 50 GHz. The four-port coupler uses a traditional multi-hole and split block design to a achieve 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. Custom coupling levels are available under different model numbers.
