Abstract
State-of-the-art 1.244-GHz surface transverse wave (STW) resonators on AT-cut quartz are characterized, They demonstrate an unloaded Q of 81 44 which is as high as 97% of the material Q limit for surface acousti c waves (SAW's). By analyzing the measured data and accounting for the ohmic loss, it is shown that the material Q for STW's on quartz, expe rimentally obtained from these devices, is at least 37% higher than th e material Q for SAW's.
