Abstract
An acoustic wave filter component can include an acoustic wave device including a multi-layer piezoelectric substrate. The multi-layer piezoelectric substrate can include at least a support substrate and a piezoelectric layer. The acoustic wave device can include an interdigital transducer electrode on the piezoelectric layer. An additional layer can be located over the interdigital transducer electrode. The acoustic wave filter component can also include a bulk acoustic wave resonator supported by the additional layer. The acoustic wave device can be a boundary wave resonator, and one or more boundary wave resonators may be provided in a stacked arrangement, with the bulk acoustic wave resonator in the top layer of the stacked arrangement. The acoustic wave device can also be a temperature-compensated surface acoustic wave device.
