Model SWD-0340H-28-BB is a Ka band, four-port waveguide bi-directional coupler that delivers a 3 dB nominal coupling level and 35 dB minimum directivity across the full waveguide band from 26.5 to 40 GHz. The bi-directional 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-28 waveguides with UG-599/U flanges. Other coupling levels are available under different model numbers.
