3-Port Directional Coupler

SWD-2020H-03-SB is WR-03, three-port waveguide directional coupler that delivers a 20 dB nominal coupling level and 20 dB typical directivity across the full waveguide band from 220 to 330 GHz. The three-port coupler uses a traditional multi-hole and split block design to achieve a flat coupling level, and low insertion loss. The interfaces of the coupler are WR-03 waveguides with UG-387/U-M anti-cocking flanges. Custom coupling levels are available under different model numbers.
