摘　　要：文中介绍了驱动延时组件在雷达中的工作原理,进行延时组件的宽带、小型化和高精度设计。基于低温共烧陶瓷与微波多层板层叠的结构,将延时与驱动电路集成设计。利用宽带幅度均衡技术、宽带幅相精度调节技术进行高精度延时设计。最终实现了宽带小型化高精度驱动延时组件的研制。根据实测结果,在3 GHz^6 GHz频率范围内幅度带内平坦度优于±0.4 dB,延时相位精度≤±5°,延时幅度精度≤±0.5 dB。In this paper,the working principle of drive time-delay module in radar system is introduced.Wideband,miniaturization and high accuracy design of time-delay modules is given.The cooperation of microwave multilayer printed circuits board and low temperature co-fired ceramic is adopted to implement integration design of true time-delay and drive circuit.On a basis of wideband amplitude equalized technique and wideband amplitude/phase accuracy fine-tuning methods,high accuracy time-delay is warran-ted.Consequently,a wideband miniaturized high accuracy drive time-delay module is designed.According to the measured results,at the frequency band of 3 GHz^6 GHz,amplitude fluctuation is better than±0.4 dB,time-delay phase accuracy is within±5°,and time-delay amplitude accuracy is within±0.5 dB.
