Abstract

The invention provides a W-band continuous wave traveling wave tube which comprises an electron gun, a slow wave circuit arranged at one end of the electron gun and a four-stage depressed collector connected with the output end of the slow wave circuit, the slow wave circuit comprises a tube shell and a folded waveguide high frequency arranged in the tube shell; two pieces of attenuation porcelainin the middle of the folded waveguide high frequency and two energy transmission windows connected with the two ends of the folded waveguide high frequency are arranged, an input magnetic screen assembly is arranged at one end of the tube shell, and an output magnetic screen is arranged at the other end of the tube shell. According to the invention, a multi-section jump structure folded waveguideslow wave circuit is adopted, a four-stage depressed collector is designed for an eccentric notch, 50W power output in a continuous wave state can be realized, the working state is stable, and the total efficiency of the whole tube is greater than 18%.

Description

technical field [0001] The invention belongs to the field of microwave technology, in particular to a W-band continuous wave traveling wave tube. Background technique [0002] As a commonly used power amplifier, traveling wave tubes are widely used in radar, electronic countermeasures, communications, medical electronics and other fields. At the forefront, it has been widely used in radar, guidance, electromagnetic countermeasures, tactical and strategic communications, deep space detection, imaging and biological effects. Existing helical TWTs and coupled-cavity TWTs cannot meet the needs of subsequent rapid development in the W-band, so it is necessary to design and develop a high-efficiency W-band folded waveguide TWT. Contents of the invention [0003] The purpose of the present invention is to propose a W-band continuous wave traveling wave tube. [0004] The technical solution to realize the object of the present invention is: a W-band continuous wave traveling wav...
