Abstract:
A package that includes a first filter comprising a first polymer, a substrate cap, a second filter comprising a second polymer frame, at least one interconnect, an encapsulation layer and a plurality of through encapsulation vias. The substrate cap is coupled to the first polymer frame such that a first void is formed between the substrate cap and the first filter. The second polymer frame is coupled to the substrate cap such that a second void is formed between the substrate cap and the second filter. The at least one interconnect is coupled to the first filter and the second filter. The encapsulation layer encapsulates the first filter, the substrate cap, the second filter, and the at least one interconnect. The plurality of through encapsulation vias coupled to the first filter.
