Abstract
This paper introduces four kinds of 2 GHz surface transverse wave resonators with low insertion loss, low Q on Y-rotated cuts of quartz perpendicular to the x-axis. There are same configure and number of transducers, reflector number, metal thickness via wave length.There are only difference that the number of short grating, and result in much difference. One of these can be 2.493 GHz, 7.8 dB of insertion loss, 4.89 MHz bandwith of 3 dB.
