Abstract : The acceleration-sensitivity of AT-cut resonators has a marked dependence on blank curvature. As the plate contour becomes flatter, the acceleration sensitivity coefficient decreases approximately linearly with diopter value. Four types of AT-cut resonators were studied: 5 MHz fundamental mode, 5 MHz third-overtone, 10 MHz third-overtone, and 20 MHz fundamental mode. Biconvex units of given contour have been found not to have a substantially lower acceleration sensitivity than plano-convex units of the same contour. No relationship has been observed between blank curvature and acceleration sensitivity for SC-cut resonators. A large number of fundamental mode and third overtone AT and SC-cut designs have been evaluated. To date, the acceleration sensitivities of the best AT-cut designs are no worse than that of the best SC-cut designs. (Author)
