一种多注速调管发射机的设计

Design of a Multibeam Klystron Transmitter

介绍了一种多注速调管发射机。在数百千瓦功率电平上,多注速调管具有频带宽、工作电压低、体积小、重量轻、增益和效率高等特点,可根据系统要求,设计出性能不同的发射机,所以许多雷达选用多注速调管作为末极发射管。文中对多注速调管的使用、高压电源和控保电路进行了阐述,着重介绍了栅极调制器设计方法及刚管的参数选择,最后给出本系统的测试结果。

This paper introduces a kind of transmitter using multi-beam klystron. In the range of hundreds kilowatt power. Multi-beam klystron has a lot of characters, such as broadband,low operating voltage,small size,light weight,hign gain and effi ciency. So that many radars choose multi-beam klystron as transmitter＇s last amplifier. The employing of multi-beam klystron,highvoltage supply power and control circuits are described in the paper, grid modulator＇s design and the hard tube parameters choosing are especially introduced. Finaliy, the result of testing is given out.
