Abstract:
A compound acoustic wave filter device comprises a support substrate having an including two or more circuit connection pads. An acoustic wave filter includes a piezoelectric filter element and two or more electrodes. The acoustic wave filter is micro-transfer printed onto the support substrate. An electrical conductor electrically connects one or more of the circuit connection pads to one or more of the electrodes.
