Abstract
A device includes a resonator stack. The resonator stack includes a first chiplet including a first acoustic resonator having a first resonant frequency and a second chiplet including a second acoustic resonator having a second resonant frequency that is different from the first resonant frequency. The device also includes a substrate coupled to the resonator stack, and electrical interconnections between the first chiplet and the second chiplet to provide a conductive path between the first acoustic resonator and the second acoustic resonator.
