4-Port Directional Coupler

SWD-4025H-06-DB is a D-band, four-port waveguide dual-directional coupler that delivers a 40 dB nominal coupling level and 25 dB typical directivity across the full waveguide band from 110 to 170 GHz. The dual-directional coupler uses a traditional multi-hole and split block design to achieve a flat coupling level, high directivity, and low insertion loss. The waveguide interface of the coupler is WR-06 waveguides with UG-387/U-M anti-cocking flanges. Other coupling levels including custom coupling levels and asymmetrical forward/reverse coupling levels are available under different model numbers.
