摘要
使用高度集成的射频芯片R1000代替大量分立元件,来完成整个射频电路的询问、接收和中频接收机的设计。该设计极大地简化了系统,提高了系统的性能和稳定性;同时增加了外部PA设计,从而大大增加了读写器的读写距离。
Using highly integrated RF chip R1000 to replace a large number of separate components,the inquiries,receiving and IF receiver of the RF circuit are designed.It greatly simplifies the system design and improves system performance and stability.The external PA is designed to increase the reader＇s read/write range.
