Abstract: In this letter, a 1.7–6.5-GHz reactively matched power amplifier (RMPA) is designed using a 0.2- μ m gallium nitride (GaN) high-electron mobility transistor (HEMT) process. To achieve an ...

Power amplifier (PA) is the core device for dc-RF conversion in wireless power transfer (WPT) system. However, the drain efficiency (DE) of PA decreases significantly due to the load mismatch effect ...
