摘　　要：T/R多功能芯片是相控阵雷达中的关键元器件,包含射频、数字以及驱动等电路模块,其电性能和功能评估过程极为复杂。在电性能及功能评估过程中,要求数字时序控制信号能够灵活配置,被测量电路的输入时序与其响应结果能一一对应,数字回读信号能直观显示。基于FT245RNL USB接口芯片和EP4CE10E22C8 FPGA,设计了一种针对T/R多功能芯片评估的控制电路,结合矢量网络分析仪、源表等仪器,完成了对芯片电性能和功能的评估。结果表明,上位机应用软件能准确地控制数字信号的收发。该方案在T/R多功能芯片评估系统的数字设计上表现出良好的通用性,为该类电路的评估提供了一种比较实用的思路。T/R multifunctional chip is the key component in phased array radar,including RF,digital and drive circuit modules,and its evaluation process of electrical performance and function is very complicated.In the evaluation process of electrical performance and function,it is required that the digital timing control signals can be flexibly configured,the input timing of the measured circuit can correspond to its response one by one,and the digital readback signal can be displayed intuitively.Based on FT245RNL USB interface chip and EP4CE10E22C8 FPGA,a control circuit for the evaluation of T/R multifunctional chip is designed,and the electrical performance and function of the chip are evaluated by combining vector network analyzer,source meter and other instruments.The results show that the upper computer application software can accurately control the transmission and reception of digital signals.The scheme shows good universality in the digital design of T/R multifunctional chip evaluation system,and provides a practical idea for the evaluation of such circuits.
