Abstract

The invention discloses an inclined multi-path synthetic gyrotron traveling wave tube TE02 mode input coupler, and belongs to the technical field of microwave and millimeter wave devices. The input coupler comprises a power distribution part, an inclined multi-path synthesis part and a cut-off circular waveguide. According to the invention, a high-purity TE02 mode is coupled in a main circular waveguide by adopting an inclined multi-path synthesis structure, and by changing the number and position distribution of the branches of rectangular waveguides on the side wall of the main circular waveguide and the included angle between the branches of the rectangular waveguide on the side wall and the circular waveguide, the field distribution of the main competitive modes (TE01 and TE41) of a TE02 mode in the main circular waveguide is destroyed to improve impedance matching, so that the beneficial effects of effectively suppressing a parasitic mode, reducing a reflection coefficient, improving conversion efficiency and increasing bandwidth are achieved.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave devices, and in particular relates to an oblique-entry multi-channel synthesis convoluted traveling wave tube TE 02 mode input coupler. Background technique [0002] The cyclotron traveling wave tube is a high-power, wide-band microwave and millimeter-wave amplifier with high power and wide-band characteristics. It has broad application prospects in millimeter-wave imaging radar, millimeter-wave communication systems, and electronic warfare. The input coupler is one of the core components of the gyrotraveling wave tube, and its main function is to connect the TE of the standard rectangular waveguide 10 The modes are coupled out of the gyro TWT working mode TE in the circular waveguide through specific mode conversion mn mold. It is the core high-frequency device that completes the mode conversion of the input signal and modulates the energy or speed of the cyclotron beam. ...
