Abstract
Film bulk acoustic resonator having suppressed lateral mode. In some embodiments, a film bulk acoustic resonator can include a piezoelectric layer having a first side and a second side, a first electrode having a first lateral shape implemented on the first side of the piezoelectric layer, and a second electrode having a second lateral shape implemented on the second side of the piezoelectric layer. The first and second lateral shapes can be selected and arranged to provide a resonator shape defined by an outline of an overlap of the first and second electrodes. The resonator shape can include N curved sections joined by N vertices of an N-sided polygon. The resonator shape can be configured to have no axis of symmetry.
