4-Port Dual-Directional Coupler

220 to 330 GHz, 10 dB Coupling, 20 dB Directivity, WR-03 Waveguide
SWD-1020H-03-DB is a WR-03, four-port waveguide dual-directional coupler that delivers a 10 dB nominal coupling level and 20 dB typical directivity across the full waveguide band from 220 to 330 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-03 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.
