3-Port Directional Coupler

SWD-0340H-15-SB is a V band, three-port waveguide 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 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-15 waveguides with UG-385/U flanges. Other coupling levels are available under different model numbers.
