Spurious-Free Shear Horizontal Wave Resonators Based on 36Y-Cut LiNbO 3 Thin Film.

This article presents lithium niobate (LiNbO 3 ) based on shear horizontal (SH0) resonators, utilizing a suspended structure, for radio frequency (RF) applications. It demonstrates the design, analysis, and fabrication of SH0 resonators based on a 36Y-cut LiNbO 3 thin film. The spurious-free SH0 resonator achieves an electromechanical coupling coefficient (kt2) of 42.67% and a quality factor (Q r ) of 254 at the wave-propagating orientation of 0° in the 36Y-cut plane.
