Embodiment Construction

[0030] A Ka-band circular waveguide TE01 mode exciter, such as Figure 1-3 As shown, the mode exciter consists of five parts: the first part is the orthogonal waveguide, the second part is the rectangular step waveguide, the third part is the uniform square waveguide, the fourth part is the bone-shaped step waveguide and the fifth part is the uniform circular waveguide.

[0031] The first part, the orthogonal waveguide, consists of two rectangular waveguides. The two rectangular waveguides include a standard rectangular waveguide that runs through front and back and an overmodulated rectangular waveguide 1-2. One port of the overmoded rectangular waveguide 1-2 is opened on its side wide surface, and the other port is opened on its rear end surface. The standard rectangular waveguide is vertically arranged on the wide side of the overmodulated rectangular waveguide 1-2, and the central axis of the standard rectangular waveguide of the orthogonal waveguide intersects the centr...

Abstract

The invention discloses a Ka wave-band circular waveguide TE01 mode exciter. The exciter is formed by an orthogonal waveguide, a rectangular step waveguide, a uniform square waveguide, a bone-shaped step waveguide and a uniform circular waveguide. One port of the orthogonal waveguide forms an input port of the mode exciter. The other port of the orthogonal waveguide is connected to the port of the rectangular step waveguide, wherein the port of the rectangular step waveguide has a small size. The port of the rectangular step waveguide is connected to one port of the uniform square waveguide, wherein the port of the rectangular step waveguide has a large size. The other port of the uniform square waveguide is connected to the port of the bone-shaped step waveguide, wherein the port of the bone-shaped step waveguide has a small size. The port of the bone-shaped step waveguide is connected to one port of the uniform circular waveguide, wherein the port of the bone-shaped step waveguide has a large size. The other port of the uniform circular waveguide forms an output port of the mode exciter. The exciter possesses characteristics that conversion efficiency is high; a mode purity is high; the structure is compact; and easy processing and a broadband are achieved.

Description

technical field [0001] The invention relates to the technical field of mode exciters, in particular to a Ka-band circular waveguide TE01 mode exciter. Background technique [0002] According to the circular waveguide TE01 mode ( Mode) field structure distribution, it can be known that it has the following characteristics: (1) It is an axisymmetric mode, and there is no polarization degenerate mode; (2) The transmission loss is low, and the loss decreases with the increase of frequency; (3) With less number of mode competitions, the mode conversion process can be simplified. Due to the above characteristics, Modes are widely used in high power microwave devices. in, The mode is regarded as the working mode of the partial gyrotron. Since the working mode output by the gyrotron cavity cannot be used directly, it is impossible to cold test the performance of the system, such as the Q value and frequency of the resonant cavity, and the test of the transmission and reflect...
