{AI Talks with Tea&Coffee #48} Distinguished Microwave Lecturers Series: High-Frequency Doherty Power Amplifiers: Challenges and Design Methodologies
Abstract: Doherty power amplifiers are widely used to achieve high efficiency with high-PAPR signals, but their extension to millimetre-wave frequencies is far from trivial. At high frequency, classical Doherty assumptions no longer hold, and efficiency, gain, bandwidth, linearity, and implementation constraints become strongly interdependent. This lecture provides a design-oriented perspective on the key challenges limiting high-frequency Doherty operation and discusses practical methodologies to address them. Topics include gain behaviour, on-chip power combination, bandwidth limitations, and linearity degradation, with emphasis on architectural trade-offs rather than idealized solutions. The discussion is supported by measured GaN MMIC examples for 5G and satellite applications, showing that successful high-frequency Doherty designs rely on balanced co-design choices rather than isolated performance optimization. Short Bio: Vittorio Camarchia is an Associate Professor at the Department of Electronics and Telecommunications, Politecnico di Torino, Italy. His research focuses on high-efficiency and high-linearity RF/microwave power amplifiers for 5G/6G and satellite communications, with emphasis on load-modulated architectures, including Doherty, Chireix and LMBA amplifiers, GaN/GaAs MMIC design, and broadband linearization. He is Track Editor for MWTL, Chair of IEEE MTT-S TC-23 Wireless Communications for 2025–2026 and an IEEE MTT-S Distinguished Microwave Lecturer for 2026–2028.
