Problems solved by technology

The power and frequency of electromagnetic waves are a pair of contradictions. As the operating frequency of the device increases, its output power will drop sharply. It is difficult to ensure that it works at a high frequency while achieving a large output power.

Abstract

The invention discloses a staggered double-line planarized traveling-wave tube with a high power, high frequency and high-order mode operation. A forward staggered double-line high-frequency structureis employed to realize high coupling impedance and enhance beam-wave interaction, so that high-power electromagnetic waves are output. In the specific using process, the high-order mode of working inthe W waveband (70-110 GHz) is achieved by reasonably setting working parameters, so that the frequency band of the novel traveling wave tube is greatly improved, the two key points of high power andhigh frequency are well balanced, and the high-power, high-frequency and high-order mode working mode of the traveling wave tube is achieved.

Description

technical field [0001] The invention belongs to the technical field of traveling wave tubes, and more specifically relates to an interleaved double-line planar traveling wave tube working in a high-power, high-frequency, high-order mode. Background technique [0002] The development of science and technology has always had a great demand for high-power and high-frequency electromagnetic waves. Especially with the large-scale commercial use of 5G communication networks and the pre-research of future 6G communication technologies, high-power electromagnetic wave emission sources are always a key problem. Traditional electromagnetic wave emission sources mainly use solid-state devices, which mainly use electron migration inside semiconductors to amplify electromagnetic wave signals. However, due to their inherent weaknesses, this type of electronic device has always been unable to generate high-power, high-frequency electromagnetic wave signals. Vacuum electronic devices using ...
