Abstract :
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.
