Abstract
A method for creating a four-port quadrature coupler suitable for monolithic implementation which involves connecting two ports of a balun, suitable itself for implementation in monolithic microwave integrated circuits, to two separate phasing networks. A device exhibiting the proper four-port quadrature coupler characteristics within a MMIC structure results, with wide bandwidth exceeding one octave.
