Abstract

This invention refers to a high power microwave power amplifier, which contains driving circuit, insulated gate bipolar transistor, capacitor, pulse transformer and solid state power supply, wherein the two insulated gate bipolar transistors are serially connected between driving circuit and pulse transformer, capacitor set between insulated gate bipolar transistor and pulse transformer, insulated gate bipolar transistor is used as the switch of capacitor charge or discharge, high power pulse is generated by the instant discharge of capacitor, the solid state power supply is 28-500v, high voltage power supply is 1000-1600w. Said invention directly generates high power voltage by low voltage power supply for the normal work of klystron and greatly raises power supply efficiency.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a high-power microwave power amplifier. technical background [0002] The high-power microwave transmitter uses a klystron as a high-power microwave output element to provide high-power microwave signals to the antenna. When the cathode modulation pulse klystron is used, it needs a high-voltage and high-current switching pulse to modulate the cathode, so that the klystron works in the switching state and outputs microwave pulses at regular intervals. The classic method is to use a hose modulator, which is excited by an artificial line and a hydrogen thyratron to form a switching pulse. After the 3000 volt voltage is boosted to 20,000 volts by a pulse transformer, the high voltage pulse current required by the pulse klystron is provided. . Under the condition that the volume, weight and power consumption are strictly limited, its disadvantage is that the artificial line is re...
