| Abstract: | Temperature is the main parameter that affects the stability of surface acoustic wave (SAW) devices such as the external and internal stress. The temperature sensitivity of the frequency as a function of quartz crystal anisotropy is presented by a perturbation equation because of a temperature change. The analytical result shows which cut is suitable for high temperature sensitivity of the quartz and which cut is associated with low temperature sensitivity. The theoretical sensitivity values are compared with experimental results. Both the experimental and theoretical results are in good agreement. |
