ABSTRACT:
There is disclosed a six-port hybrid microwave coupler comprising three inputs and three outputs which are isolated from each other and matched such that a signal applied to any one of the inputs produces signals on all three of the outputs, said signals being orthogonally distributed in phase and uniformly distributed in amplitude. The coupler has a plane configuration of transmission lines with an inner ring comprising three similar segments with the interconnection points of the segments constituting three input or outlet first ports of the coupler. The coupler also has an outer ring comprising three similar segments with the interconnection points of the segments constituting three outlet or input second ports, respectively, of the coupler. The coupler also has three radial branches connecting the interconnection points of the inner ring segments to corresponding interconnection points of the outer ring.
