ABSTRACT:
A frequency selective component and a method for making a frequency selective component. The frequency selective component includes a substrate having at least a first surface and an acoustic impedance transformer coupled to the substrate. The acoustic impedance transformer transforms an acoustic impedance of the substrate to a second acoustic impedance. The acoustic resonator further includes a mechanical resonator disposed on the acoustic impedance transformer. The acoustic resonator provides a frequency selection function.
