A double Volterra series approach to analyze nonlinear microwave circuits is presented, with special emphasis on FET mixers. Considering a FET as a circuit with two input ports, a procedure to obtain closed‐form expressions for nonlinear transfer functions is presented. Based on this approach, the known time‐varying Volterra series technique can be demonstrated. Calculated conversion loss and two‐tone IMD for a FET‐resistive mixer are successfully compared with already published data. © 2003 Wiley Periodicals, Inc.
