  • Abstract
    High overtone lateral field resonators, fabricated on -16.5° rotated Y-cut LiTaO3 plates, were examined for high- Q operation in the frequency range between 300 MHz and 1000 MHz. QF products of up to 5×1013 for unmounted plates and for hard-mounted plates have been measured. The QF product is higher than can be achieved with quartz, and the self-noise levels of these resonators compare favorably with those of the lowest-noise SAW (surface acoustic wave) resonators. The electrode design of these energy-trapped resonators is discussed
