A differential SiP (LNA-filter-mixer) in silicon technology for the SKA project

This paper describes two filters realised in a technology entirely dedicated to passive components and which allows active dies flip-chip by means of bumps. Then, it presents the design of a SiP (system in package) constituted of a differential LNA (low noise amplifier) and mixer flipped respectively in front and back of a balanced filter. Measurements of a SiP, where just the LNA is flipped onto the filter, are shown in the last part.
