Theoretical Analysis and Experimental Verification of Intermodulation Distortion Generated by a Surface Acoustic Wave Device Exhibiting an Anomalous Power Law
This article investigates intermodulation distortion (IMD) signals generated in a temperature-compensated surface acoustic wave (TC SAW) duplexer, which exhibits an anomalous power law. Numerical calculations show that the IMD products are strongly correlated to the ratio of the two input powers. It is also shown that input frequencies selection hardly affects the IMD products. An approximate model is derived for both third- and fifth-order IMDs. The accuracy of this model is then validated by comparing its predictions with measured third- and fifth-order IMDs from the TC SAW duplexer.
