Improving Power Amplifier Efficiency and Linearity Using a Dynamically Controlled Tunable Matching Network

This paper presents a tunable matching network that enhances both efficiency and linearity of power amplifiers (PAs). A medium-power amplifier with a varactor-based matching network is designed, fabricated, and tested. It is demonstrated that not only the power efficiency at reduced drive levels can...
