Title:
SURFACE ACOUSTIC WAVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/155305
Kind Code:
A1
Abstract:
A surface acoustic wave element (10) comprises a substrate (101) containing an LiNbO3 piezoelectric monocrystal, a first dielectric layer (122) provided on the substrate (101), and an IDT electrode (121) provided on the first dielectric layer (122). A high-frequency signal is propagated in the substrate (101) using Rayleigh waves.
