摘要
结合ISO18000-6c的RFID系统标准,提出其读写器的设计方案。阐述了读写器的硬件设计,介绍了射频发送与接收单元的电路结构,并运用混频器直接下变频的方式对915 MHz信号进行解调,简化了解调电路。仿真测试结果说明该设计方案可满足实际RFID应用系统的需要。
The design of the RFID reader/writer was proposed based on the RFID system＇s ISO18000-6c standard It illustrated hardware design of reader/writer and circuit configuration of transmit block and receive block. Receive block demodulated 915MH signal by mixer direct-down-conversion which simplified demodulation circuit. The design can satisfy RFID apply system by simulation test.
