4-Port Dual-directional Directional Coupler

SWD-4040H-12-DB is an E-band, four-port waveguide dual-directional coupler that delivers a 40 dB nominal coupling level and 40 dB typical directivity across the full waveguide band from 60 to 90 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-12 waveguides with UG-387/U flanges. Custom coupling levels are available under different model numbers.
