10%带宽兆瓦级速调管放大器
A TEN PERCENT BANDWIDTH HIGH-POWER PULSED KLYSTRON AMPLIFIER

摘要: 正 长期以来,人们对雷达发射机用的兆瓦级末级发射管的效率-带宽特性和增益-带宽特性一直很感兴趣。而且雷达对发射管相位-频率线性,增益平坦性和功率幅值平坦性的要求也越来越高。但是目前微波管产品中,尚没有在这样的功率电平下带宽宽于10％的管子。由于速调管在大功率、高增益、高效率等方面与其他微波管相比,仍占有较大的优势,因此,近十几年来,国际上许多微波管公司,厂家在展宽速调管带宽方面仍进行着不少具有实际意义的研究工作

Abstract: This paper describes a pulsed klystron amptifier tube with 1-2 MW peak out-put power is described. It operates at the low end of S-band. The 1 dB bandwidth is greater than 10% f0 with 40 dB gain. The tube has an overlapping mode extended interaction output section and a six cavity buncher section. It is very stable in operation. It has nearly constant gain accross the entire band. -
