摘要
设计一种射频识别读写器,包括射频收发芯片、巴伦电路、功率放大电路、衰减器、低通滤波器、耦合器、收发天线、微控制器模块、RS232接口和USB接口。该射频识别读写器通过优化电路的设计以及相关组件、电路和模块的合理选型,使得整个射频识别读写器的工作稳定,能够准确地进行信息读取,应用范围广,实用性强。
This article designed a radio frequency identification reader. It contains RF transceiver chip,Ba Lun circuit,Power amplifier circuit,attenuator,low pass filter,coupler,transmit and receive antenna,microcontroller module,RS232 interface and USB interface. Through the optimization of the circuit design and the reasonable selection of the related components,circuit and module,the RFID reader this article proposed made the whole RFID reader work stable and be able to read information accurately. It is very practical and widely used.
