摘　　要：为满足机载综合前端宽带数据高速射频采样和激励合成的要求,以及解决传统接收激励器平台方案中接收激励与信号处理未分离和传输数据带宽不足两大问题,提出了新型多通道宽带接收激励器设计方案。该方案不仅实现了多通道500 Msample/s高速模数、数模转换,还通过对接收激励通道及高速数据接口逻辑巧妙设计实现了在接收端完美复原传输端数据流信号,实现了FPGA的4x高速吉比特传输接口与后端信号处理FPGA之间最高可达10 Gb/s的高速点对点数据通信,实现了真正意义上的多通道宽带接收激励功能,具有推广意义。To satisfy the demand of high speed wideband radio frequency sampling and signal synthesizing in airborne frontend equipment and also solve transceiver isolation with signal processing and limit of trans-mission bandwidth of traditional solutions, a novel multi-channel wideband transceiver solution is provid-ed. High speed digital-to-analog converter （ DAC ） and analog-to-digital converter （ ADC ） working at 500 Msample/s are used. Perfect recovery of data signal at receiver-end is realized through receiving and simulating channel logic interface design. Inter-FPGA data communication between transceiver and signal processor is transferred at 10 Gb/s at most. The true multi-channel wideband transceiver function is real-ized and it will find wide applications in high speed wideband communications.
