ABSTRACT:
A piezoelectric resonator having a rectangular resonator body cut from a piezoelectric crystal in accordance with a rotated X-cut. One of the end faces bounding the major surfaces is intended for mounting, whereas in the vicinity of the other end face an electrode array is arranged. The electrode array in conjunction with the crystal cut have been selected so that a combined resonant mode is generated, comprising an XY' thickness-shear vibration and a thickness vibration in the X or Y' direction.
