摘　　要：简要介绍了UHF RFID国际标准ISO/IEC18000-6C、EPC Global C1G2及ETSI的空中射频接口要求,采用∑-△调制小数分频PLL频率合成方案,应用LMX2541及ADF4360-8芯片设计了一频率范围在860~960MHz内可跳变的UHF RFID读写器用频率合成器。仿真及实验结果表明,其各项指标均达到或超过ISO/IEC18000-6C、EPC Global C1G2及ETSI标准规定的要求,可以满足未来通用型UHF RFID读写器的应用需求。In this paper,the air RF interface specification requirements for ISO/IEC18000-6C、 EPC Global C1G2 and ETSI standards that are used for UHF RFID system are briefly introduced.The sigma-dalta fractional-N PLL synthesizer is adopted.The LMX2541 and ADF4360-8 are used to realize a set of frequency synthesizer that is used for UHF RFID reader/writer,and ranged in 860～960MHz frequency hopping.It is indicated by simulation and experimental results that the various technical indices reaches or exceeds the requirements specified in the Technical Requirements of ISO/IEC18000-6C、EPC Global C1G2 and ETSI standards,and meet future universal UHF RFID reader/writer applications.
