Abstract:
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.
