Overcoming Efficiency and Linearity Challenges in 6G RF Power Amplifiers
Radio frequency (RF) power amplifiers (PAs) are fundamental components in nearly all wireless transmitters, from tiny sensors and mobile phones to high-power base stations. Their primary function is to boost RF signals by converting DC power into amplified radio waves, ensuring reliable transmission over distances. As 6G aims to enable transformative applications such as ultra-high-speed communication, massive IoT, and immersive experiences, PAs must address challenges in energy efficiency, broadband operation, and linearity under high peak-to-average power ratios and dynamic traffic. This talk explores the critical obstacles and emerging solutions in 6G PA development, including advanced architectures, novel materials like Gallium nitride (GaN) MMIC, new frequency bands (e.g., FR3), and AI-driven optimization techniques. It also highlights innovations in linearity enhancement, system integration, and system-level co-design. By bridging theoretical insights and practical applications, this talk provides a roadmap for researchers and engineers to pioneer RF PA technologies that meet the stringent requirements of 6G, paving the way for a more connected and efficient wireless future.
