Mi-Wave’s 567 Series Dual-directional Couplers are broadband, broadwall components with a multi-hole directivity. The 567 Series Couplers are available in 3, 6, 10, 20, 30, 40 and 50 dB coupling values for standard waveguide bands from 18 to 170.0 GHz.

Applications

The 567 Series Dual-directional couplers are used in applications that require precise sampling of both incident and reflected energy. The 3 dB couplers are especially useful in balanced mixer work where broadband power division of RF and LO signals is required to supply both sides of a balanced mixer unit. The 3 dB bi -directional couplers can provide full bandwidth power division.
