ABSTRACT:
A piezoelectric boundary acoustic wave (PBAW) device includes a slotted dielectric body disposed over one surface of a piezoelectric body and electrodes forming an IDT at the interface between the piezoelectric body and the dielectric body. The thickness of the electrode is set so that the acoustic velocity of the boundary acoustic waves is less than acoustic waves propagating in the piezoelectric body.
