Abstract :
The paper deals with the influence of the third harmonic injection into the grid and anode qirclits of a tuned high power amplifier, in order to improve the efficiency. The linear triode model is used, enabling avaluation of all power balance important parameters in a closed form. The results obtained are compared with the performances of the same amplifiers, without injection.
