Input and Output Controlled High-Efficiency PAs

This presentation discusses the design of efficiency-enhanced PAs by concurrently controlling input and output harmonics. In GaN-based PAs, a significant efficiency degradation occurs if the input harmonics are not terminated at optimum condition. The objective of the work is to reveal the impact of input nonlinearity on performance and investigate possible design methodologies to minimize efficiency degradation by simultaneously controlling input and output harmonics. The practical validation and results are shown for GaN 1.95 mm using the Focus Harmonic MPT system.
