title: Cubic temperature dependence for SAWs on X-cut quartz.
abstract: A cubic dependence of frequency on temperature has been experimentally observed for surface-acoustic-wave (SAW) delay lines fabricated on X-cut quartz. The SAWs propagate on the X-cut surface in a direction between the positive Y direction and the Z direction, 33.44 degrees from the +Y axis. An experimental system is described for measuring the temperature sensitivity of the delay lines. The measurements show that the relative position of the delay-line transducers has a strong influence on both the frequency versus temperature curve and the insertion loss versus temperature curve.
