Abstract

Hybrid filters and more particularly filters having acoustic wave resonators (AWRs) and lumped component (LC) resonators and packages therefor are described. In an example, a packaged filter includes a package substrate, the package substrate having a first side and a second side, the second side opposite the first side. A first acoustic wave resonator (AWR) device is coupled to the package substrate, the first AWR device comprising a resonator. A plurality of inductors is in the package substrate.
