Problems solved by technology

[0004] In the existing technology, the Chebyshev tapered structure has the strongest ability to suppress the miscellaneous modes. The disadvantage is that the main design idea of ​​the Chebyshev tapered waveguide is to suppress the coupling of the working mode to the parasitic mode, and does not suppress the reflection of the working mode as a The main considerations lead to severe reflection in the working mode, which reduces the output power of the gyro TWT

Abstract

The invention relates to the technical field of microwave electronic devices, in particular to a coupling output segment of a gyrotron traveling wave tube amplifier. The coupling output segment is connected with a high-frequency interaction segment and comprises a first output segment body and a second output segment body, wherein the first output segment body and the second output segment body both satisfy the requirements of a Chebyshev tapered waveguide structure, the first output segment is connected with the second output segment, and the radius of the tail end of the first output segment is equal to the initial radius of the second output segment. According to the coupling output segment of the gyrotron traveling wave tube amplifier, the reflection of a working mode TE01 and mode coupling from the working mode TE01 to a higher-order mode TE02 can be effectively suppressed, and the transmission performance of the gyrotron traveling wave tube amplifier is improved.

Description

technical field [0001] The invention relates to the technical field of microwave electronic devices, in particular to a coupling output section of a gyrotron traveling wave tube amplifier. Background technique [0002] The coupling output section of the gyrotron TWT is a tapered waveguide structure connecting the high-frequency interaction section and the load, and the high-power microwave signal is transmitted to the load device through the coupling output section. The coupling output section is the key component of the gyro TWT, which directly affects the output power and the beam interaction efficiency. Such as figure 1 As shown, for the gyrotron TWT whose working mode is TE01 mode, in the transmission process, it is necessary to minimize the coupling of working mode TE01 to miscellaneous modes TE02 and TE03 to ensure the mode purity of the output signal. Since terminal reflection is one of the important reasons for self-excited oscillation, the design of the coupling o...
