Theoretical Analysis and Experimental Verification of Intermodulation Distortion Generated by a Surface Acoustic Wave
Abstract:
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.

Sound Waves: Interference
Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
Interference and Superposition of Waves
Interference occurs in mechanical waves, such as sound waves, waves on a string, and surface water waves. Mechanical waves correspond to the physical displacement of particles. Hence,...
