The invention discloses a traveling wave tube pulse power amplifier output radio frequency pulse signal overshoot elimination device which comprises a control module, a two-way delay controllable pulse signal generation module, a modulatable pre-stage amplifier, a high-voltage power supply, a pulse traveling wave tube and a signal source. According to the device provided by the invention, the overshoot of the output radio frequency pulse signal of the traveling wave tube pulse power amplifier can be eliminated only by setting the delay of the two paths of pulse square wave signals output by the double-path delay controllable pulse signal generation module in the control module, so that the pulse top flatness of the output signal of the traveling wave tube pulse power amplifier is improved;the circuit is simple in structure, and can quickly eliminate overshoot of a radio frequency pulse signal output by the traveling wave tube pulse power amplifier.
Description
technical field [0001] The invention belongs to the technical field of power amplifiers, and in particular relates to an overshoot elimination device for a radio frequency pulse signal output by a traveling wave tube pulse power amplifier. Background technique [0002] At present, the overshoot phenomenon of the output radio frequency pulse signal of the traveling wave tube pulse power amplifier at home and abroad is mainly caused by the fluctuation of the grid modulation voltage of the high-voltage power supply, which causes the overshoot phenomenon of the output pulse signal of the pulse traveling wave tube. Although this phenomenon can be solved by adding a high-voltage capacitor filter at the output end of the high-voltage power supply, the added high-voltage filter capacitor will increase the volume of the high-voltage power supply on the one hand. For high-power pulse power amplifiers that require multiple traveling wave tubes to achieve The volume of the high-voltage ...
