Consist of double-ridge primary and secondary waveguide sharing a common broadwall where multi-hole arrays provide the required coupling level in the forward direction relative to the input wave and high directivity in the reverse direction.
A measurement device that is inserted into the transmission line between an RF source—such as a signal generator, vector network analyzer, or transmitter—and a load.
Are passive devices used to perform many functions, including splitting and combining signals in amplifiers, switching circuits, and antenna beam-forming networks.
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.
