Abstract

Structures of a system on a chip are disclosed. In one embodiment, the system on a chip (SoC) includes an RF component disposed on a first part of a substrate, a semiconductor component disposed on a second part of the substrate, the semiconductor component and the RF component sharing a common boundary, and a conductive cage disposed enclosing the RF component. The conductive cage shields the semiconductor component from electromagnetic radiation originating from the RF circuit.
