3d stacking of multilayer piezoelectric substrate filters and integrated passive devices

A wireless mobile device comprising:

• one or more antennas;
• and
• a radio-frequency module that communicates with the one or more antennas, the radio-frequency module including a multi-stack acoustic wave device having a substrate having one or more first electrodes and one or more second electrodes, a first die having a first portion having one or more electrodes and a second portion positioned away from the first portion, the one or more electrodes of the first die being coupled to and electrically connected with the one or more first electrodes of the substrate, and a second die having a first portion having one or more electrodes and a second portion positioned away from the first portion, the one or more electrodes of the second die being electrically connected with the one or more second electrodes of the substrate via one or more bonding wires, the first die being positioned between the second die and the substrate, the second portion of the first die being coupled to the second portion of the second die.
