PHN. 9676 11 ABSTRACT: A piezoelectric resonator with a rectangular body out from a piezoelectric crystal in accordance with a rotated X-cut such that the major surfaces are perpen- dicular to the Z'-axis. Two opposite end faces of the body perpendicular to the X or Y'-axis. One of said end faces is intended for supporting the body, whereas in the direct vicinity of the other end face an electrode array is provided in such a way that a combined resonant mode is obtained, comprising an XY' thickness-shear vibration and a thickness vibration in the X or Y' direc- tion. Due to this combined resonant very small resonators are achievable.
