摘　　要：超宽谱功率源合成需要精确控制各个源的相位,传统的移相器无法实现在超宽频带内精确控制移相,为了满足功率源合成的要求,本文设计了一种高精度可延时同步脉冲产生系统,该系统主要是基于FPGA和数控延迟芯片设计实现的,其信号同步和时间延迟精度优于100ps。Ultra-wide spectrum power source synthesis requires precise control of the phase of each source. Traditional phase shifters cannot achieve precise control of phase in ultra-wideband. In order to meet the requirements of power source synthesis, a high-precision delayed Synchronization Pulse generation system is designed in this paper. The system is mainly based on FPGA and digital delay chip design, its signal synchronization and time delay accuracy is better than 100 ps.
