摘要
在阐述了RFID技术的基础上,分析了RFID读写器在零中频接收机中的应用原理,给出了RFID应用中因标签位置变动会产生接收盲点、以及信号直流偏移等关键问题的解决办法,同时进行了实际电路的测试与验证。
On the basis of elaborating RFID technology, the application principle of RFID reader in the zero-IF receiver is analyzed. The solutions of receiving blind spot, IX; offset of signal and other key problems come out of label position change in RFID application are proposed. At the same time, the testing and verification of actual circuit are performed.
