MONOLITHIC PIEZOELECTRIC FILTER Russian patent published in 1995 - IPC

Abstract RU 2047268 C1

FIELD: electroacoustics. SUBSTANCE: monolithic piezoelectric filter has piezoelectric plate 1 whereon are formed at least two acoustically coupled point-to-point resistors in the form of spherical projections 2 with their bases spaced apart at distances selected from definite condition. Electrodes are applied to projections on opposite side of plate. Relation between distanced for bases of spherical projections 2 and thickness of plate 1 in its flat portion is given in description of invention. EFFECT: enlarged functional capabilities. 5 dwg
