摘　　要：介绍了当前远距离无线汽车门开关RKE(Remote Kevless Entry)的现状、工作原理以及其发展前景。认为RKE是无线电通信技术与机械汽车技术的完美结合,是无线控制的一个很好的应用。叙述了MAXIM1470和MAXIM1472芯片的特征和关键属性,以及它们的应用电路图。根据这两种芯片的特点和远距离无线汽车门开关的性能要求,以及现在市场上客户对产品的要求,基于这两个芯片在价格和性能上的优势,设计出了基于MAXIM1470和MAX- IM1472芯片的RKE,它适合批量产品的设计和生产要求。The developing stale and principle of current remote keyless entry and its prospect are introduced. It is a perfect integration between technology of wireless communication and mechanical technology of the car. It is also the great application of wireless control. The cliaracteristic and key properly and its applied circuit of maxim 1470 and maxim 1472 are recommended. The remote keyless entry has been designed based on maxim 1470 and maxim 1472, according to the performance of remote keyless entry and characteristic of the two CMOS chip and the desire of customer in the market of this product. It is suitable for desigin and products.
