Abstract

Based on the network matrix conversion from scatter parameters to admittance parameters, a novel analysis method for multiport passive components is presented. Unlike the traditional even- and odd-mode analysis only being used for symmetrical structure, this kind of method is no limited. In this paper, three examples, such as Wilkinson power divider, 180° ring hybrids and quadrature (90°) hybrids with arbitrary port impedances are researched. Analysis results show that design formulas obtained from new method agree with ones reported by class literatures, but the calculation process is much simpler than class methods obviously.
