Abstract
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 ).
