The Mi-Wave 567 series of dual directional couplers are broadwall components with a multi-hole directivity that operate up to 110 GHz. It is available in 3,6, 10, 20, 30 and 40 dB coupling values. The dual directional couplers can be used in applications that require precise sampling of both incident and reflected energy. These components are very useful in balanced mixers where broadband power division of RF and LO signals is required to supply both sides of a balanced mixer unit.
