摘要

本文研究了温度补偿表面声波（TC SAW）双工器中产生的互调失真（IMD）信号，它表现出反常的幂律。数值计算表明，IMD积与两个输入功率之比密切相关。输入频率的选择对IMD结果几乎没有影响。导出了三阶和五阶imd的近似模型。然后，通过将该模型的预测结果与TC SAW双工器测量的三阶和五阶imd进行比较，验证了该模型的准确性。

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.
