| Abstract: | This paper considers the frequency-quadrupling three-cavity
gyroklystrons with successive frequency-doubling in each cavity. The
cavities of 225~GHz frequency-quadrupling gyroklystron are designed
with the scattering matrices method and the possible operating mode
are discussed. With the point-gap theory, the starting currents of
the possible operating modes and the potential parasitic modes in the
output cavity are calculated. The optimal operating mode is proposed
under consideration of the mode competition and the power capacity
of the cavity. |
