Abstract :
This paper reports the development of an X-band to Ku-band klystron frequency multiplier that can double input frequency and amplify input power simultaneously. A seven-cavity klystron was designed, in which the X-band output section was replaced by a smaller Ku-band one. The electron optics of this new klystron was almost the same with that of an X-band klystron. The experimental results showed that the peak output power of 30 kW can be reached at pulse voltage of 33 kV, with an efficiency value of 15% at 35 kV.
