MIKON 2024 Short Course

Microwave Power Amplifiers: from theory to design

The aim of this SC is to provide an overview of all aspects related to the design of basic microwave power amplifiers (PAs).

The SC is organized in two parts.

The first part is focused on the theoretical concepts required to understand the behavior of a PA. The definition of power match condition and the main issues involved in a PA design will be discussed. The main feature and theoretical performance attainable from a single active device will be analyzed, introducing the harmonic manipulation concepts for high efficiency designs (e.g., the class F, J, 2nd harmonic tuned, etc.). Several practical examples of PA designs will be shown highlighting the pros and cons related to the harmonic tuning strategies.

Then, in the second part of the SC, a practical example of the design through CAD tool of a monolithic microwave (MMIC) PA design will be presented, showing how the theoretical concepts are considered during the implementation. This part will also focus on the major challenges, such as stability (small and large signal) and how to address these in amplifier design.
