摘　　要：分析了X波段有源相控阵雷达子阵驱动延时组件的功能及其工作原理,介绍了驱动延时组件高精度与小型化设计的实现方式。针对任务需求,设计并实现了一种集成五位延时、收/发增益补偿功能的驱动延时组件。根据实测结果,该驱动延时组件接收增益为16 d B±1 d B,发射功率为27.5 d Bm±0.5 d Bm,延时切换时幅度精度≤±0.8 d B,相位精度≤±5°。The function and working principle of the subarray drive time-delay module,applied in X-band multifunctional active phased array radar are analyzed. The solutions for high accuracy design and miniaturization of drive time-delay module are also introduced. According to the task requirements,a drive time-delay module is designed and realized,integrating 5-bit time-delay,receive and transmit gain compensation. According to the measured results,the drive time-delay module achieves the receive gain within 16 d B±1 d B,transmit power within 27. 5 d Bm±0. 5 d Bm,time-delay amplitude accuracy better than±0. 8 d B and time-delay phase accuracy better than ±5°.
