Surface acoustic wave resonator having comb electrodes with different overlapping lengths |
摘要 |
A surface acoustic wave resonator includes a piezoelectric substrate, a first surface acoustic wave resonator having a comb electrode provided on the piezoelectric substrate, and a second surface acoustic wave resonator having a comb electrode provided on the piezoelectric substrate. The first surface acoustic wave resonator and the second surface acoustic wave resonator are apodized and connected in parallel. |
