Abstract

The invention provides an output waveguide window for a Ka-waveband high-power space traveling wave tube. The window comprises a window piece, a sealing piece, a waveguide flange and a transition waveguide, and is characterized in that the sealing piece sleeves the outer side of the window piece and is connected with the circumference of the window piece in a sealing manner; the waveguide flange is connected with the upper side of the sealing piece; the transition waveguide sleeves the lower side of the sealing piece and is hermetically connected with the sealing piece; and a vacuum cavity isformed in the sealing piece, the waveguide flange and the transition waveguide. The structure is simple, the reliability is high, and the requirements of small standing wave, temperature impact resistance, mechanical vibration resistance and good heat dissipation performance of the traveling wave tube are met.

Description

technical field [0001] The present disclosure relates to the field of microwave electric vacuum devices, in particular to an output waveguide window for a Ka-band high-power space traveling wave tube. Background technique [0002] The traveling wave tube is a microwave tube that realizes the amplification function by continuously modulating the speed of the electron beam. The microwave signal to be amplified enters the slow wave circuit through the input window and travels along the slow wave circuit. The electrons exchange energy with the traveling microwave field, so that the microwave signal is amplified, and then output through the output window. Therefore, the output window of the traveling wave tube directly affects the loss of the traveling wave tube, the quality of the characteristic impedance matching, and the narrow frequency bandwidth. [0003] With the improvement of band bandwidth, output power, reliability, and thermal design (including loss and heat dissipati...
