Effect of second rotation on frequency-temperature characteristics of AT-cut crystals
Abstract
AT-cut quartz plates, the most widely used vibrators for frequency selection and control, are singly rotated cuts. Increasingly stringent requirements on frequency tolerances motivate the report, which examines the effect on frequency-temperature behavior of small but nonnegligible second rotations that arise from inevitable manufacturing variations. The results presented permit formulation of practical and consistent specifications of tolerances on both angles to achieve a required temperature coefficient.
