Abstract
An acoustic wave component includes a layer system having a piezoelectric layer and a first metal layer arranged on the piezoelectric layer, a first resonator having a first electrode in the first metal layer, where the first metal layer includes electrode structures periodically arranged in a direction of propagation of a wave through the acoustic wave component, and a second resonator coupled to the first resonator and electrically isolated from the first resonator. The layer system includes a waveguide for guiding a guided bulk acoustic wave in a lateral direction of the acoustic wave component.
