Abstract
PURPOSE: To obtain the complex function parts to be used to the quadrature detection device by providing the split partial electrode to excite the thickness shear volume wave provided at the 2nd region of the piezoelectric substance.
CONSTITUTION: Piezoelectric substance 1 possesses 1st region 2 polarized vertically to the main plane and 2nd region 3 polarized parallel to the main plane respectively. In addition, cross-finger electrodes 6 and 7 capable of transmission and reception of the Rayleigh wave are provided at region 2, and split partial electrodes 8 and 9 are provided at region 3 to excite the thickness shear volume wave. Thus the complex function parts can be obtained for the filter and the detection element which are used to the FM signal detection device, especially to the quadrature detection device.
