Abstract :
This paper reports the development of an X-band to Ka-band klystron frequency multiplier that can triple the input frequency and amplify the input power simultaneously. A 7-cavity klystron was designed, in which the X-band output section was replaced by a smaller Ka-band one. The electron optics of this new klystron was nearly the same as that of an X-band klystron. The experimental results showed that a peak output power of 14 kW can be reached at a pulse voltage of 36 kV, with an efficiency of 3.9%.
