Design & study of quadrature hybrid 4 port network for matching, isolation, and coupling around the operating frequency

Quadrature hybrid 4 Port network (Branch Line couplers (BLC's)) is an electronic device which used for dividing the power in the various RF network. Due to high frequency application in the recent days it is to be quantified to build an extension version and quality in fabrication which provides high-performance component. In this paper, we are providing an outline of Microwave power dividers and couplers, with parameters like matching, isolation and coupling around the given operating frequency.
