Power & RF

Develop wireless power transfer, RF power amplifier and power device technologies.

The Power & RF team is involved in a wide range of research challenges in wireless power transfer, RF power amplifiers and power devices. For wireless power transfer, we are focusing on magnetic technologies that could achieve efficiencies that are very close to those of cabled power transfer. To address the pressing issue of an increasingly congested and fragmented wireless spectrum, we are exploring digital and analog technologies for power amplifiers that could provide the agility and speed of allocating frequency and bandwidth with maximum power efficiency and linearity. Complementing the research in power amplifiers, we are pursuing experimental and theoretical research on the basic physical mechanisms that limit power device performance and reliability. From these efforts, device models are modified to optimize circuit design and new power device design and architectures are explored to bring performance to the next level.
