Abstract

The invention relates to an energy coupling device suitable for a rectangular-crossed double-gate slow-wave structure, belonging to the technical field of vacuum electronics. One end of the device is connected with a rectangular waveguide, and the other end is connected with a rectangular-crossed double-gate slow-wave structure; the part connected with the rectangular-crossed double-gate slow-wave structure comprises an upper row and a lower row of rectangular gate waveguide structures which are mutually staggered and distributed and have gradually changed height; the half-height positions of the rectangular gates at the upper row are in an upper datum plane (1); all half-height positions of the rectangular gates at the lower row are in a lower datum plane (2); counted from a port connected with the rectangular-crossed double-gate slow-wave structure, the heights of the upper row and the lower row of rectangular gates are gradually reduced to zero; and the maximum height of the rectangular gates does not exceed the rectangular gate height of the rectangular-crossed double-gate slow-wave structure. The invention has the advantages of favorably coupling a microwave signal into the rectangular-crossed double-gate slow-wave structure, favorably extracting the amplified microwave signal from the rectangular-crossed double-gate slow-wave structure and being easy to connect with a traditional standard waveguide device.

Description

technical field [0001] The invention belongs to the technical field of vacuum electronics, in particular to an input-output structure in a rectangular interlaced grid traveling wave tube. Background technique [0002] Traveling wave tube is the most important type of microwave source in the field of vacuum electronics technology. It has the characteristics of high power, high efficiency, high gain, broadband and long life. It is widely used in radar, guidance, satellite communication, microwave remote sensing, and radiation measurement. And other fields, its performance directly determines the level of equipment. The core component of a traveling wave tube is a slow wave structure. Commonly used slow-wave structures include helix, coupling cavity, and meander waveguide. The output power of these structures working in the submillimeter wave and terahertz wave bands is limited, and the structure processing is very difficult. [0003] In order to meet the needs of practical a...
