WMB: Amplify Your Knowledge: Mastering High Efficiency RF Power Amplifiers from Basics to Advanced Architectures

Presentation Abstract
RF Power Amplifiers (PAs) play a critical role in modern wireless and satellite communications, radar, and electronic systems, requiring a deep understanding of both fundamental principles and cutting-edge innovations. This advanced course is designed for PhD students and professional researchers seeking to expand their expertise in RF PAs design, analysis, and optimization. Starting from solid-state power amplifiers fundamentals, the course will cover theoretical concepts, including PA classes of operation, their Figures of Merit, stability considerations and efficiency enhancement techniques. Special emphasis will be placed on advanced PA architectures, including Doherty PA, Envelope Tracking and other PA architectures, which are critical for next-generation wireless and satellite communication systems. The course will also address broadband design challenges and emerging trends in integrated PAs for large-scale phased array applications. Linearization strategies, including digital predistortion (DPD), will be discussed as essential tools to mitigate distortion and improve spectral efficiency. Several design examples based on commonly used semiconductor technologies (eg GaN, GaAs etc) will be presented to highlight the link between theory and practical implementation. Through a combination of theoretical foundations, practical case studies, and research-driven discussions, attendees will gain the expertise needed to design, model, and optimize cutting-edge RF power amplifiers. By the end of the course, participants will be well-equipped to contribute to breakthrough innovations in PA technology, bridging the gap between academic research and industrial applications.
