Abstract :
Novel surface acoustic wave filters have been developed by depositing SiO2 and ZnO thin films onto 90° rotated ST-cut quartz crystal substrates. Up to 19 dB insertion loss improvement was obtained for the filter with a ZnO film. The filters have no coupling with other wave propagating modes, exhibiting only one passband
