Description

technical field [0001] The invention relates to the technical field of a gyrotron traveling wave amplifier and a gyrotron return wave tube of a high-power broadband millimeter-wave device, and is a novel high-frequency circuit structure for mutual conversion between a rectangular waveguide mode and a circular waveguide circular electric mode. Background technique [0002] The gyrotron is a millimeter-wave and quasi-millimeter-wave high-power coherent radiation source based on the electron cyclotron maser (ECM) mechanism. Energy microwave weapons and other aspects have great application value, and the international community attaches great importance to its theoretical and experimental research. For the cyclotron TWT, its broadband amplification characteristics require a broadband input coupling circuit to cooperate; for the broadband continuous tuning cyclotron return wave tube, its high-frequency field energy needs to be fed to the load through a broadband output coupling c...
