High-power broadband pulse multiple-beam klystrons with output from100 kW up to 1000 kW with a bandwidth up to 12

摘要

High-power transmitting devices of radar systems are requiredfrequently to supply levels of pulse output power from a hundred up tothousand kilowatt and an average output power of the order of 10 kW.Moreover, the radar transmitters should be maximum broad bandwidth tosatisfy the requirements of anti-jamming and electromagneticcompatibility. The common requirement for klystrons used in thesetransmitters is the requirement of a low level of feeding voltages (beamvoltage and modulation voltage). Multiple-beam klystron (MBK) design,which is based on the fundamental mode operation of resonators, has goodperspectives for application in high-power transmitters. Some results ofthe developments of high-power multiple-beam klystrons operating in thefundamental resonator mode executed per the last decade are consideredin the this paper
