Goal(s)

The need for wireless devices with improved battery life, smaller form factor, and reduced cost is driving research towards flexible RF Front-End Modules (FEM) with a high integration level to efficiently afford multimode multi-band requirements. Today’s RF FEM are mostly addressed by multiple modules using a large set of technologies which lead to large and costly solutions. As the push for further cost and size reduction goes on, many research activities and industrial efforts are currently on going to improve RF FEM integration level by introducing new technologies and design techniques. The proposed teaching module will provide an overview of technologies and advanced design techniques for the implementation of high performance tunable RF building blocks and RF FEM.
