Abstract :
Designed and measured characteristics of "hiccup" and non-synchronous surface acoustic wave resonators on quartz are presented and analyzed. In "hiccup" configuration basic periodicity of interdigital transducer and reflectors is the same except for additional distance of a quarter of wavelength in between neighboring electrodes at the center of transducer. The configuration with different periods of transducer and reflectors is called as non-synchronous. The hiccup SAW resonators show significant degradation of quality factor that can be attributed to radiation of bulk waves. Measured characteristics of non-synchronous resonators agree well with calculations.
