Abstract
The application of only 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 (HFHPTAs). Under the specific conditions that are presented in this paper, the injection of two harmonics into a carrier signal can increase output power and efficiency.
