SAW velocities in X-cut LiTaO/sub 3/

Abstract

Due to recent interest in SAW devices based on propagation in 112.2' Y-rotated X-cut LiTa03 the SAW propagation velocity in the entire X-surface has been characterized by laser probe measurements. Results obtained include velocities for free and shorted surfaces. Also metal loading influence on velocity has been measured. The results are given as trigonometric expansions with tabulated coefficients.
