摘　　要：介绍了一款基于便携式模拟源的X波段射频收发系统的设计实现方法,该射频收发系统具有TDD通信方式、敏捷变频、小型化等特点。系统采用多芯片微组装技术实现上行电路、下行电路、频率源以及电源控制电路一体化,大大降低了系统体积。为了实现不同应用场景的应用要求,系统可通过FPGA配置实现收发共用天线以及收发不共用天线的工作方式。系统的工作频率在X波段,接收动态范围大于90 dB,接收灵敏度优于-90 dBm,下行链路增益0~30 dB,增益FPGA可控,上行链路增益大于24 dB,谐波抑制度优于-47 dB。This paper introduces the design and implementation method of an X-band RF transceiver system based on portable analog source.The RF transceiver system has the characteristics of FDD communication mode,agility frequency conversion and miniaturization.The system uses multi-chip micro-assembly technology to realize the integration of uplink circuit,downlink circuit,frequency source and power control circuit,which greatly reduces the volume of the system.In order to meet the application requirements of different application scenarios,the system can realize the working mode of sending and receiving shared antenna and sending and receiving non-shared antenna through FPGA configuration.The operating frequency of the system is in the X-band,the receiving dynamic range is greater than 90 dB,the receiving sensitivity is better than-90 dBm,the downlink gain is 0~30 dB,which is controllable by FPGA,the uplink gain is greater than 24 dB,and the harmonic suppression degree is better than-47 dB.
