Abstract
An acoustic wave filter (10) and a method (30) of forming the acoustic wave filter (10) are disclosed. The acoustic wave filter includes a substrate (20) supporting a first die (18) and a second die (18). The first die (18) and second die (18) include either a Surface Acoustic Wave (SAW) resonator or a Bulk Acoustic Wave (BAW) resonator, wherein one of the resonators is configured as a series resonator (12) of the acoustic wave filter (10) and the other resonator is configured as a shunt resonator (14) of the acoustic wave filter (10).
