SURFACE ACOUSTIC WAVE RESONATOR

摘要

A surface acoustic wave resonator of the present invention includes a piezoelectric substrate (10), a first surface acoustic wave resonator (20) having a comb electrode (11) provided on the piezoelectric substrate (10), and a second surface acoustic wave resonator (30) having a comb electrode (12) provided on the piezoelectric substrate (10). The first surface acoustic wave resonator (20) and the second surface acoustic wave resonator (30) are apodized and connected in parallel.
