Ku波段高效率脉冲行波管的研制

摘要

The Ku-band high efficiency pulse TWT(Travel Wave Tube)had been manufactured and its design,CAD simulation and test results were also presented. On the basic of CAD software the election gun, magnetic focus system,helical slow wave circuit beam wave intersection and electrion beam collector,of which this TWT consists, have been optimazed that the pulse TWT is continually improved in the period manufacture processing. The manufectured travel wave tubes meet the technical specifications for their proper use in the developing rada system. The high efficiency, high output are realized in this TWT, that the pulse output power is more than 2. 2 kW and officieney oves 30% at the condition of the same driven power and 2 GHz frequency range of Ku-band.%简要介绍了Ku波段高效率脉冲行渡管的设计、CAD计算和测试结果.通过对电子枪、聚焦系统、慢波电路、电子注和慢波线高频场大信号互作用的计算、收集极的设计,获得了符合新雷达系统技术指标要求的整管.实测结果为:在Ku波段2 GHz频带范围内,等激励、脉冲输出功率大于2.2 kW、效率大于30％.
