Abstract
A multiplecavity klystron, which has a wide range of frequencies in which it can be used and is capable of operating at high frequencies, comprises first and second resonant cavities. At least one of resonant frequencies in TEM and TE11 modes of the second resonant cavity is lower than the operating frequency of the first resonant cavity, and the other of resonant frequencies in TEM and TE11 modes of the second resonant cavity is different from the operating frequency of the first resonant cavity.
