摘要
整流器、时钟提取电路、调制电路和解调器等主要模块,符合ISO/IEC14443TypeB协议的非接触IC卡射频接口电路的基本构成,列举并分析了具体的电路实现形式。对于TypeB射频接口电路的设计具有参考和指导意义。
A design method of wireless data transmission system based on MCU AT89C51 is presented. The system design take Nordic nRF401 chip as core. The performance parameters,the system structure and use method of nRF401 are analyzed. The design proposal of software and hardware is p and given realization method of low-power and reliability of system. The system designed by this method has many features, such as the small-power to launch, little external components. It can meet the design needs of low-power and microminiaturization wireless data transmission system.
