FIELD: radio-electronics; piezoelectronic industry.
SUBSTANCE: proposed high-frequency piezoid designed for use in manufacturing oscillators, filters, and other volume acoustic wave devices operating in frequency band of 50 to 1000 MHz is distinguished by open-type inverted mesa layout. Piezoid is made in the form of shaped monolithic piezoelectric wafer with thinned vibrating region. Wafer is polyhedral in shape having vertical T- or L-section, its active region being confined in crystallographic planes (XZ).
EFFECT: enhanced electrophysical parameters and minimized size of devices built around proposed piezoid.
