    Abstract

    This paper proposes a precise nonlinear simulation technique for surface acoustic wave (SAW) duplexers, especially for the in-band 3rd order nonlinear distortion, the so-called triple beat. The model is based on the nonlinearity of SAW stress vs. strain (nonlinear elasticity), and needs just one nonlinear parameter, which represents the 3rd order nonlinear coefficient for the elastic constant. The simulation results for 1.9 GHz Personal Communications Service (PCS) SAW duplexers demonstrate fairly good agreement with the measurements with a discrepancy of only 1 dB.
