摘　　要：利用真空管峰值功率大、效率高等优势,对基于X波段行波管的高功率发射组件进行了研究。文中详细介绍了8通道发射组件设计、高压组件小型化封装及幅相一致性控制等关键技术,并基于以上技术研制了一种8通道X波段行波管发射组件。该组件采用一套电源同时给8只管子供电的集成化设计方法,既提高了组件功率密度,减小了发射组件体积,又能够满足雷达阵面的要求。通过对发射组件各通道幅相一致性调整,进行了8通道功率合成试验测试,试验数据达到预期的目的,进一步验证了文中所提技术的可行性。该组件是一种新型的行波管放大器发射组件,体积小,功率密度大,且价格相对便宜,为相控阵雷达发射单元提供了新的解决途径。Taking advantage of high peak power and high efficiency of vacuum tube,the high-power transmitting module based on X band traveling wave tube is studied.The key technologies such as the design of 8-channel transmitting module,miniaturized packaging of high-voltage module and amplitude phase consistency control are introduced in this paper and an 8-channel traveling wave tube transmitting module is developed based on these technologies.The module adopts an integrated design method that uses a set of power supply to simultaneously power 8 tubes,which improves the power density of the module,reduces the volume of the transmitting component,and meets the requirements of the radar array.By adjusting the amplitude and phase consistency of each channel of the transmitting module,an 8-channel power combining test is conducted.The test data achieves the expected results and the feasibility of the proposed technology is further verified.The module is a new type of traveling wave tube amplifier transmitting module,which has a small size,high power density and relatively low price,and provides a new solution for phased array radar transmitting unit.
