High-frequency generator with harmonic-tuned resonant circuits

摘要

In order to improve the efficiency of a self-starting high-frequency generator, where for self-starting power is fed back from the anode circuit to the control grid of the grid-controlled electron tube used as amplifier element, the following measures are provided. An additional oscillating circuit (LA3, CA3) which is tuned to a multiple of the operating frequency (f1) is arranged in the anode circuit. An oscillating circuit (LG31, LG32, CG3) tuned to a multiple of the operating frequency (f1) is likewise arranged in the control-grid circuit. Components (LG31) belonging to the feedback circuit are at the same time components of the oscillating circuit arranged in the control-grid circuit.
