PULSE AMPLIFIER SHF Russian patent published in 2017 - IPC H03F3/00 

FIELD: electricity.

SUBSTANCE: device containing a TWT, an anode power source (APS), a collector power source (CPS), a filament power source (FPS), a barrier voltage source (Ubar), a cutoff voltage source (Ucut), a modulator and a diode, the first output of the sources is connected to the TWT cathode and the second output respectively - to the slow-wave structure (SWS), collectors and the TWT filament and the modulator outputs, the modulator output is connected to the diode anode, which cathode is connected to the other output of the voltage source Ubar, a commutator, a current sensor, a resistor and the second diode are included. In this case, the output of the modulator through the current sensor is connected to the CE TWT, one output of the current sensor is connected to the TWT cathode, and the other output is connected to the input of a commutation switch. The first output of the commutation switch is connected to the TWT cathode, and the second output is connected through the resistor to the source Ubar, the modulator input and the cathode diode, the anode of which is connected to the modulator key, commutating the voltage of the source Ucut.

EFFECT: increase the reliability of the device.
