4-Port Bi-directional Directional Coupler

SWD-5038531040H-15-BB is a V band, four-port waveguide bi-directional coupler that delivers a 10 dB nominal coupling level and 30 dB minimum directivity across the full waveguide band from 50 to 85 GHz. The four-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-15 waveguides with UG-385/U flanges. Custom coupling levels are available under different model numbers.
