Waveguide Type Cross Guide Directional Couplers

Low Cost • Low VSWR • Four-port Device • Broadband Operation


Mi-Wave’s 566 Series Cross Guide Coupler Consists of two waveguides at right angles to each other, joined by small coupling slots whose size, location, and orientation determine the coupling and directivity of the unit. All ports are available for sampling or injecting energy and are clearly marked to indicate the coupling direction.


The 566 Series Cross Guide Directional Couplers provide an efficient means for sampling power or injecting a signal into a waveguide transmission line.
