Abstract
A device includes: a first electrode having a first electrode thickness; a first acoustic propagation layer disposed on the first electrode, the first piezo-electric layer having a first acoustic propagation layer thickness; a second electrode having a second electrode thickness; a second piezo-electric layer disposed on the first electrode, the second piezo-electric layer having a second acoustic propagation layer thickness; and a third electrode having a third electrode thickness, wherein the second electrode thickness is between 1.15 and 1.8 times the first electrode thickness. The first and third electrode thicknesses may be equal to each other, and the first and second piezo-electric layer thicknesses may be equal to each other. The first and third electrodes may be connected together to provide two acoustic resonators in parallel with each other.
