Abstract
A superlattice crystal resonator having a substrate of a dielectric acoustic superlattice material, both sides of which substrate are plated with electrodes. The resonator can be a one-port resonator if the electrode on both sides is a single electrode, or it can be a two-port resonator if the electrode on one side is a single electrode and the electrode on the other side is a bipolar electrode. The superlattice crystal resonator can be used as a superlattice crystal filter, either in the form of a monolithic superlattice crystal filter formed by a two-port superlattice crystal filter, or in the form of a combined superlattice crystal filter where a number of one-port superlattice crystal resonators are interconnected in various circuitry configurations with or without other electronic components, such as capacitors, inductors, and resisters.
