Surface acoustic wave filters with extremely narrow bandwidth are urgently needed for use in security communication systems. The working frequency of the surface acoustic wave filter will drift significantly at extremely high or low ambient temperatures, which makes it hard for the filter to effectively extract useful signals and suppress noise in the near-passband. This study simulated and analyzed the frequency-temperature characteristics of extremely narrow bandwidth surface acoustic wave filter based on a quartz substrate and studied the effects of metal thickness and the metallization ratio of electrodes on the inflection point of the secondorder temperature characteristic of the device. An extremely narrow bandwidth surface acoustic wave filter with low frequency drift was finally manufactured by optimizing the structural parameters.
