摘要：

A two-port SAW resonator has been designed for a stabilizing element of an SAW liquid sensor. There is increasing use of SAWs for sensors, and most of the works reported on sensors to date are concerning delay lines. In this paper, SAW resonators have been studied in order to reduce an acoustic loss and a distortion of the delay lines. SH type SAWs are excited on a 36-degrees YX LiTaO3 substrate by using IDTs. The two port SH-SAW resonators have been used for sensing the liquid. The sensitivity of the SAW resonance frequency and Q value for the viscosity of liquids have been measured.
