research overview

  • Dr. Barton’s RF Power Laboratory investigates engineering challenges related to RF and microwave active circuit design. Currently, the group is working on making RF front-ends and related components more energy efficient. Our research in novel MMIC and hybrid power amplifier architectures addresses the performance tradeoffs (such as linearity vs. efficiency) in conventional designs. Examples include a novel RF-input load modulated balanced amplifier topology and related techniques employing load modulation, as well as reconfigurable RF front-ends. By manipulating low-power, phase-controlled inputs of multiple nonlinear but efficient PAs whose outputs are combined in a non-isolating network, simultaneous efficiency and wide-range output power control can be achieved. This approach extends to other RF applications requiring high performance such as phased-array systems and wireless power transfer, and relates to techniques employed in high-frequency power electronics.
