Abstract
Embodiments of the invention include a piezoelectric resonator which includes an input transducer having a first piezoelectric material, a vibrating structure coupled to the input transducer, and an output transducer coupled to the vibrating structure. In one example, the vibrating structure is positioned above a cavity of an organic substrate. The output transducer includes a second piezoelectric material. In operation the input transducer causes an input electrical signal to be converted into mechanical vibrations which propagate across the vibrating structure to the output transducer.
