4-Port Bi-directional Directional Coupler

SWD-3030H-08-BB is a F band, four-port waveguide bi-directional coupler that delivers a 30 dB nominal coupling level and 30 dB nominal directivity across the full waveguide band from 90 to 140 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-08 waveguides with UG-387/U-M anti-cocking flanges. Custom coupling levels are available under different model numbers.
