摘　　要：给出了一种1输入6输出频标分配电路的设计及硬件实现。采用电压串联负反馈电路实现信号的放大及分配，闭环增益稳定性比开环增益稳定性提高了1＋A0F 倍；通过 PCB 布线优化设计，补偿通道间时延差。测试结果表明，设计的频标分配电路可满足1~140 MHz 的频标信号分配。A frequency signal distribution circuit with one input and six outputs is designed and implemented . The stability of the close loop gain is 1＋A0F times of that of the open loop gain , when the distribution circuit is designed with a voltage series negative feedback amplifier . The differential group delay between channels is decreased by optimization design of the PCB wiring . Test results show that the frequency distribution circuit may be used to the frequency signals range from 1 MHz to 140 MHz .
