Split-Block Waveguide Directional Couplers
Delivers a 3 dB nominal coupling level and 25 dB nominal directivity across the full waveguide band from 110 to 170 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-06 waveguides with UG-387/U-M flanges. Other coupling levels are available under different model numbers.
