Abstract
A surface acoustic wave resonator includes: a piezoelectric substrate; an IDT electrode unit provided on the piezoelectric substrate, the IDT electrode unit being configured to perform at least one of conversion of an electrical signal into a surface acoustic wave on the piezoelectric substrate and conversion of the surface acoustic wave into an electrical signal; a reflection unit disposed in a propagation direction of the surface acoustic wave generated from the IDT electrode unit, the reflection unit being configured to reflect the surface acoustic wave to the IDT electrode unit, wherein the reflection unit comprises a plurality of electrically separated reflectors having different aperture lengths.
