摘要

A simple and analytical design methodology for a novel coupled-line power divider with arbitrary complex terminated impedances is proposed in this paper. Because of the usage of a single-section coupled line, the additional odd-mode characteristic impedance increases the design degree of freedom and makes the isolation structure still use a single resistor when terminated impedances are extended from real values (such as 50 Ohm) to arbitrary complex values. To design this generalized coupled-line power divider, the electrical parameters including electrical lengths and characteristic impedances can be redesigned by the provided closed-form mathematical expressions when complex terminated impedances are known. The validity of this given design methodology has been confirmed by simulation and measurement of two typical microstrip examples.
