摘　　要：针对软件无线电系统的模拟信号数字化,设计了基于FMC标准的双通道高速信号采集卡,着重讨论了信号采集卡模拟调理电路、电源系统、时钟网络等关键电路的设计方法以及数模混合系统高速PCB设计应遵循的主要原则,并设计了FPGA承载板的A/D接口逻辑。This paper designs a dual-channel high-speed signal sampling card based on FMC stand- ard for analog signal digitization of SDR system. It emphatically discusses the designing methods for analog modulation circuit, power system, clock network of signal sampling card and the main princi- ples for designing high - speed PCB of digital-analog hybrid system. Moreover, it devises A/D inter- face logic for FPGA carrier card.
