| 摘 要： | 电子标签的广泛应用对UHF RFID(超高频射频识别)阅读器的性能提出了更高的要求.低噪声放大器能降低系统的噪声和提高接收机灵敏度,是接收系统的关键部件.设计的LNA应用于UHF RFID阅读器前端,要求工作频率为900一930MHz,噪声系数小于1dB,带内增益大于15dB以及高线性度指标包括输出1dB压缩点大于15dBm和输出三阶互调点大于30dBm.结合相关设计理论,利用安捷伦科技的E-PHEMT(增强型伪高电子迁移率晶体管)ATF54143,完成了电路设计并通过ADS2006对直流偏置、输入输出匹配以及源极加负反馈进行优化等仿真,结果表明:电路的噪声系数可达到0.54dB,功率增益高达23.4dB,输入、输出匹配良好,各种线性度指标也完全符合设计要求.

| Abstract: | The widespread application of RFID tags requires higher performance of UHF RFID (Ultra High Frequency Radio Frequency Identification) reader. The Low-Noise Amplifier is to reduce the noise of system and improve the sensitivity of receiver, which is the key part of RFID receiver. The LNA designed by this paper is for the front of UHF RFID reader.The noise figure should be lower than 1dB at its operating frequency ranging from 900MHz to 930 MHz, gain >15dB,as well as P1dB >15dBm,meanwhile IIP3 >30dBm.
