Abstract

This article presents a study on calculating the conversion efficiency of a microwave rectifying circuit by using finite difference time domain (FDTD) algorithm. To properly descript the lumped device in FDTD algorithm, the nonlinear lumped network (NL^2^N)‐FDTD method is further extended to model Schottky diode placed across multiple FDTD cells. As a result, a group of formulae are obtained and applied to analyze a typical microwave rectifying circuit, including a nonlinear lumped device of Schottky diode HSMS‐282. The good agreement between FDTD analysis results and ADS simulated ones illustrates the validation of the derived formulae and method. This FDTD analytical method can be used to design and optimize rectifying circuits with high radio frequency–direct current conversion efficiency. © 2011 Wiley Periodicals, Inc.
