Abstract:
1. A component that functions with bulk acoustic waves, said component comprising: a multi-layer structure containing a resonator layer region which includes a first electrode layer arranged above and a second electrode layer arranged below and a piezoelectric layer arranged therebetween, all of said electrode layers being structured in a lateral plane to form at least two electrically isolated sub-electrodes for each electrode layer, said two sub-electrodes of respective layers being arranged over one another with said piezoelectric layer lying therebetween so as to form sub-resonators, at least two of said sub-resonators laterally arranged adjacent to one another in said resonator layer region being coupled acoustically through lateral acoustic mode; a carrier substrate on which said multi-layer structure is arranged; and an acoustic mirror arranged between said carrier substrate and said multi-layer structure.
