Abstract
Conceptual provisions for the construction of miniaturized variable parameter of high-power high-frequency broadband radio pulse amplifiers have been developed: filling frequency, duration, significant peak current and peak voltage. A circuit-based solution is proposed for constructing high-frequency radio signal of high-power amplifiers, whose frequency varies in the interval 0.1 … 20 MHz, the time duration is 1 … 10 periods of pulse filling frequency, with an output current that reaches 200 A and voltage up to 4 kV. The use of the developed powerful amplifier will allow creating and improving the instruments for ultrasonic quality control of products by electromagnetic-acoustic transducers in industry and electromagnetic transducers in medical devices using the effect of nuclear magnetic resonance, electron paramagnetic resonance, and also in measuring devices.
