3-Port Waveguide Directional Coupler

SWD-4040H-34-SB is a WR-34, three-port waveguide directional coupler that delivers a 40 dB nominal coupling level and 40 dB typical directivity across the full waveguide band from 22 to 33 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-34 waveguides with UG-1530/U flanges. Custom coupling levels are available under different model numbers.
