Abstract
New balance power analysis of HF high-power tuned amplifiers (HFHPTA) with composite drive and output signal obtained by injection of two harmonics (N and P) into the basic carrier signal (M=1) is presented in this paper. It is shown that injection of two harmonics could increase both maximum output power and maximum efficiency. The corresponding optimal composite drive and output signals possess almost flattened extrema
