Abstract.
The article
presents the results of computational modeling for double-beam X-band klystron designed
to use in the deep space communications system transmitters. As a result of
performed calculations in 1D program “AJDISK”, it was established that the new
device at an accelerating voltage of 16 kV can provide the following output
parameters: CW output power level - 24 kW, an efficiency - 33%, a bandwidth - 90
MHz and a gain - 44 dB. A structural feature of the intermediate resonators is the
using of metal rods to create a defect in the resonator, by analogy with the
photonic crystal resonators (PBG). The intermediate resonators were tuned to an
intended resonant frequency by changing a diameter and a location of these rods
in the defect zone.
Keywords: ground
deep space communication, X-band, two-barrel klystron, 3D modeling, photonic
band gap resonator, efficiency, amplification band.
