Embodiment

[0023] Such as Figure 1-3 As shown, the high-power truncated microwave output window is mainly composed of input square waveguide 1, input matching transition waveguide 2, field suppression ring 3, sealing groove 4, I-shaped dielectric window 5, output matching transition waveguide 6, and output circular waveguide The input square waveguide 1 is connected to the I-shaped dielectric window 5 through the input matching transition waveguide 2, and then connected to the output round waveguide 7 by the output matching transition waveguide 6, and all structures are coaxial.

[0024] The field suppression ring 3 structure is adopted on the input surface of the I-shaped dielectric window 5, which can effectively improve the power capacity. By adjusting the size parameters of the input matching transition waveguide 2, the field suppression ring 3, the I-shaped dielectric window 5 and the output matching transition waveguide 6, high-efficiency microwave transmission from the input squa...

Abstract

The invention discloses a high-power truncated microwave output window. The high-power truncated microwave output window comprises an input square waveguide, an input matching transition waveguide, an H-shaped dielectric window slice, an output matching transition waveguide and an output circular waveguide, which are sequentially connected, wherein the longitudinal section of the H-shaped dielectric window slice is H-shaped; one H-shaped side is connected with the input matching transition waveguide and the other side is connected with the output matching transition waveguide; and a field suppression ring is arranged on the inner wall, close to the H-shaped dielectric window slice, of the input matching transition waveguide. The field suppression ring structure is adopted by the input surface of the H-shaped dielectric window slice, so that the power capacity can be effectively improved. High-efficiency microwave transmission from the input square waveguide to the output circular waveguide can be achieved by adjusting the dimension parameters of the input matching transition waveguide, the field suppression ring, the H-shaped dielectric window slice and the output matching transition waveguide; and the high-power truncated microwave output window has the characteristics of compactness and high peak power capacity, and is suitable for partitioning and sealing in a microwave feeder system under a high-power condition.

Description

technical field [0001] The invention belongs to the technical field of high-power microwaves, in particular to the technical field of high-power microwave transmission and radiation, and specifically relates to a high-power truncated microwave output window. Background technique [0002] The output window was born with the emergence of microwave devices, which has an important impact on the power capacity, high-frequency characteristics, reliability and service life of devices and systems. It mainly plays two roles in the application of microwave electric vacuum devices: on the one hand, it completes the sealing of vacuum or gas; on the other hand, it ensures the normal transmission of microwaves with low reflection, so as to achieve the effect of normal transmission of electromagnetic wave energy. Microwave output windows are widely used in various microwave electric vacuum devices, such as high-power klystrons, gyrotrons, traveling wave tubes, etc., and are key components ...
