Abstract

The invention discloses a multi-stage gyro-traveling-wave tube amplifier which works with different modes on waves with the same frequency. The multi-stage gyro-traveling-wave tube amplifier is characterized in that the amplifier is composed of an electron beam passage (1), an input segment (2), a cut-off segment (3), an output segment (4), an output varying waveguide (5), and an output even waveguide (6). The electron beam passage (1) is connected with the input segment (2) which is in connection with the cut-off segment (3); the cut-off segment (3) is connected with the output segment (4) which is connected with the output varying waveguide (5), and the output varying waveguide (5) is connected with the output even waveguide (6). The input segment and the output segment work at the sameharmonic wave and the same frequency; the angular indexes of the work modes of the waveguides of the input segment and the output segment are the same; the input segment works on low level waveguide mode and the output segment works on waveguide mode higher than that of the input segment.

Description

technical field [0001] The invention relates to a multistage convoluted traveling wave tube amplifier with the same frequency and different modes, belonging to the technical field of high-power millimeter wave sources. Background technique [0002] High-power millimeter-wave radar has very important application prospects in national defense fields such as high-resolution radar imaging, anti-stealth, anti-low-altitude flying targets, anti-sea-skimming missiles, missile defense, and electronic countermeasures. Civilian fields such as high-energy physics also have good application prospects. To develop high-power millimeter-wave radar, it is necessary to develop a high-power millimeter-wave source first. Traditional vacuum electronic devices have encountered great difficulties in the millimeter-wave frequency band. And the gyrotron (1.Twiss R.Q., Roberts J.A.Electromagnetic radiation from electrons rotating in an ionized medium under the action of a uniform magnetic field.Aust...
