摘要: 介绍一个Ka波段分布作用速调管(EIK)发射机的实验系统，使用的核心器件是一只国产分布作用速调管样管，中心频率为35.01 GHz，脉冲输出功率为10 kW，最大工作比0.5%。该实验系统是为Ka/W波段双频毫米波测云仪发射机关键器件国产化进行的预研。实验系统一方面要对EIK样管的性能进行全面测试，对EIK样管在应用中可能存在的问题进行分析；另一方面优化发射机电路，满足EIK样管最佳工作要求。实验结果表明，国产Ka波段分布作用速调管技术取得了长足的进步，Ka波段大功率EIK发射机将进入实用阶段。Abstract: This paper describes an experiment system of Ka-band extended interaction klystron (EIK) transmitter, whose core component is a domestic extended interaction klystron with 35.01 GHz of center frequency, 10 kW of output pulsed power and 0.5% of maximum duty cycle. The experiment system is an advanced research prototype of key component localization of Ka/W band dual frequency millimeter wave cloud-meter transmitter. The performance of the prototype EIK is tested completely, and analysis of potential application problems for EIK are also included in the experiment system. On the other hand, the electrocircuit of transmitter is optimized to meet optimum work requirement of EIK. Experimental results show that enormous progress has been made on domestic Ka-band extended interaction klystron technology and in some areas EIK transmitter has reached the practical stage.
