Abstract

An acoustic resonator is described, the acoustic resonator comprising a stack of a first and a second piezoelectric body, wherein said first and second piezoelectric bodies have substantially the same spatial piezoelectric orientation, an intermediate intermediate electrode being arranged between said first and said second piezoelectric body forming a first terminal of said acoustic resonator, and first and second electrodes, wherein said first electrode is arranged such that said first piezoelectric body is arranged between said first electrode and said intermediate electrode, wherein said second electrode is arranged such that said second piezoelectric body is arranged between said second electrode and said intermediate electrode, and wherein said first and said second electrode are electrically connected to each other forming a second terminal of said acoustic resonator.
