摘要： A bulk acoustic wave resonator has an adjustable resonance frequency. A piezoelectric element is provided having first and second electrodes. A switching element is provided in the form of a MEMS structure which is deformable between a first and second position. The switching element forms an additional electrode that is selectively disposed on top of, and in contact with, one of the first and second electrodes. This causes a total thickness of the electrode of the resonator to be changed resulting in a modification of the resonance frequency of the resonator.
