• The Bulk characteristic and surface acoustic wave characteristic of LTGA was investigated and it is almost same as LGS crystal. Glass break sensor using LTGA was fabricated. The high frequency vibration signal of 60kHz which is AE wave region was successfully detected. The carrier frequency is 670MHz band in this research. This result suggests that it is possible to use in 950MHz UHF band. We use the LTGA which cut angles is same as general LGS wafer, in this research. Best angle of LTGA for SAW devises is might exist. Further sensitivity improvement can be expected by searching best angle.
