Model SWD-2030H-08-SB is an F band, three-port waveguide directional coupler that delivers a 20 dB nominal coupling level and 25 dB minimum directivity across the full waveguide band from 90 to 140 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-08 waveguides with UG-387/U-M flanges. Other coupling levels are available under different model numbers.
