An effective method is proposed to design a matching circuit for a microwave rectifier in order to manage the frequency bandwidth and the power bandwidth. Although the input impedance is affected by the nonlinear behavior of diodes with the variation of input power levels, the analysis on a variety of matching circuit configuration brings more evidence to improve the performance of rectifiers. This method has been applied in a low cost, zero-bias Schottky diode rectifier having RF-DC conversion efficiency of 55%. The nonlinear simulation of rectifier circuit and an analytic description of multiple dimensional parameters are the key to study the relation between the nonlinear performance of a rectifier and its matching circuit.
