Abstract

Several advantages of STW devices are by now well known. These include simultaneous moderately high acoustic velocity and zero temperature coefficient of frequency, along with extremely high power handling capability. In this paper we present theoretical and experimental evidence of an additional advantage of STW devices on quasi- AT-cut quartz: the intrinsic Q of such devices is superior to that of ST-cut SAW devices and AT-cut BAW devices, with the STW having Q×f≈3.25×1013 Hz.
