Waveguide-Cross Directional Couplers

MT series 3-port directional couplers are available from 3.22 to 110GHz, with coupling values of 3, 6, 10, 20, 30, and 40 dB. They have at least 35 dB directivity with VSWR 1.2:1 or less.  Our high directivity couplers are convenient for extracting or introducing a small fraction of power from and/or into a waveguide circuit without disturbing the operating characteristics of the circuit.
