Dr. Souheil Ben Smida of Heriot-Watt University

The design of RF PAs is a well-researched subject. There is a significant amount of contributions that range from active device manufacturing and modelling to the optimisation of complete transmitter systems that require digital and analogue engineering skills.

This talk will cover the very fundamental principles of a simple PA design which are essential to understand to be able to perform research and innovate in this field. Then, some PA architectures that perform in an efficient manner will be discussed and the methodology to optimise them will be explained in a simplified way. Finally, the talk will cover a couple linearisation techniques to compensate for PAs distortions and the challenges that an engineer/researcher would face to tackle the problem.
