4-Port Bi-directional Directional Coupler

SWD-0340H-15-BB is a V band, four-port waveguide bi-directional coupler that delivers a 3 dB nominal coupling level and 30 dB minimum directivity across the full waveguide band from 50 to 75 GHz. The bi-directional 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-15 waveguides with UG-385/U flanges. Other coupling levels are available under different model numbers.
