摘要

提出了一种用于ka波段相对论片状电子束行波管(TWT)的电耦合输入结构。这种新的输入结构易于实现，可以大大方便实验过程。结果表明，这种新型结构具有良好的传动特性。在30GHz ~ 40GHz范围内，反射系数S11小于-25dB，传输系数S21大于0.05dB。采用这种新型输入结构的ka波段相对论片状电子束行波管，可以产生大于1毫瓦的脉冲辐射。

A Ka-band relativistic sheet electron beam traveling wave tube using electric coupling input structure

An electric coupling input structure has been proposed for a Ka-band relativistic sheet electron beam traveling wave tube (TWT). This kind of new input structure is easily to be realized and can facilitate the experiment process very much. The results show that this kind of new structure has a good transmission characteristics. The reflection coefficient S11 is less than -25dB from 30GHz to 40GHz and the transmission coefficient S21 is bigger than 0.05dB at the same frequency range. The Ka-band relativistic sheet electron beam TWT with the new kind of input structure, can produce more than a MW pulse radiation.
