中文摘要:
      给出了一种基于现场可更换组件(LRM)结构的4通道宽带波形产生板卡设计。板卡上集成了一款高性能的现场可编程逻辑阵列(FPGA)以及4片高速数模转换器(DAC)芯片。DAC和FPGA之间为高速低电压差分信号(LVDS)接口,板卡输入输出接口选用标准二代LRM连接器。DAC采样率为4 Gsps,在2.4 GHz中频(IF)上瞬时带宽达到了1.2 GHz,信噪比(SNR)优于50 dB。该设计可广泛应用于电子战和宽带雷达系统中。
英文摘要:
      A design of 4-channel wide band wave generation based on the Line Replaceable Module (LRM) framework is presented. The card integrates a high performance FPGA and 4 Digital Analog Converter(DAC) chips. The DAC and FPGA connect each other by the Low Voltage Differential Signaling (LVDS) interface. The input and output interface of the board utilizes a 2nd generation LRM connector. The DAC sampling rate is 4 Gsps. The instantaneous bandwidth is up to 1.2 GHz at 2.4 GHz Intermediate Frequency(IF) output, and the Signal-to-Noise Ratio(SNR) is better than 50 dB. It can be applied to the radar EW and the wideband digital receiver.
