3-Port Directional Coupler

SWD-0340H-19-SB is a U band, three-port waveguide directional coupler that delivers a 3 dB nominal coupling level and 35 dB minimum directivity across the full waveguide band from 40 to 60 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-19 waveguides with UG-383/U-M flanges. Other coupling levels are available under different model numbers.
