Abstract :
The application of precise drive and output composite signals with nearly flattened maximums provides the optimal operating conditions (increasing efficiency and output power) of high frequency high-power tuned amplifiers (HFHPTA). Under the specific conditions that are presented in the paper, the harmonic injection into a carrier signal can increase efficiency.
