Surface mount device stacking for reduced form factor

Abstract:

A packaged module for use in a wireless communication device has a substrate supporting an integrated circuit die that includes at least a microprocessor and radio frequency receiver circuitry and a stacked filter assembly configured as a filter circuit that is in communication with the radio frequency receiver circuitry. The stacked filter assembly includes a plurality of passive components, where each passive component is packaged as a surface mount device. At least one passive component is in direct communication with the substrate and at least another passive component is supported above the substrate by the at least one passive component that is in the direct communication with the substrate.
