US 2026/0087221 A1 · DESIGN AND POWER-LOSS ANALYSIS METHODS FOR ACOUSTIC WAVE FILTERS

Abstract

A design method for an acoustic wave filter comprises setting up a first electrical circuit design of an acoustic wave filter having a plurality of series and shunt acoustic wave resonators, performing a power-loss analysis for each of the plurality of acoustic wave resonators separately, determining which of the acoustic wave resonators displays transient power dissipation which is most likely to lead to a thermal run-away event, setting up, based on the first electrical circuit design, a second electrical circuit design of the acoustic wave filter in which the acoustic wave resonator determined to most likely lead to a thermal run-away event is replaced with an open impedance, and performing a second power-loss analysis for each of the remaining acoustic wave resonators separately to determine which of the remaining acoustic wave resonators displays transient power dissipation which is most likely to lead to a thermal run-away event.

A design method for an acoustic wave filter, the method comprising:

setting up a first electrical circuit design of an acoustic wave filter having a plurality of series acoustic wave resonators and a plurality of shunt acoustic wave resonators;
performing a first power-loss analysis for each of the plurality of series acoustic wave resonators and the plurality of shunt acoustic wave resonators of the first electrical circuit design separately;
determining which of the analyzed acoustic wave resonators of the first electrical circuit design displays transient power dissipation which is most likely to lead to a thermal run-away event;
setting up, based on the first electrical circuit design, a second electrical circuit design of the acoustic wave filter in which the acoustic wave resonator determined to most likely lead to a thermal run-away event is replaced with an open impedance;
and
performing a second power-loss analysis for each of the remaining acoustic wave resonators of the second electrical circuit design separately to determine which of the analyzed remaining acoustic wave resonators displays transient power dissipation which is most likely to lead to a thermal run-away event.
