无线收发系统 摘　要：随着现代电子技术的飞速发展，通信技术也取得了长足的进步。在无线通信领域,越来越多的通信产品大量涌现出来。但设计无线数据传输产品往往需要相当的无线电专业知识和价格高昂的专业设备，因而影响了用户的使用和新产品的开发。nRF401是一个为433MHz　ISM频段设计的无线收发芯片，它为短距离无线数据传输应用提供了较好的解决办法, 使用nRF401降低了开发难度，缩短了开发周期，使产品能更快地推向市场。本文提出了一种应用于无线数据收发系统的设计思路及实现方案，给出了基于无线射频芯片nRF401和AT89S52单片机的无线数据传输模块的设计方法,详细分析了各部分实现原理，并对系统的传输距离、传输数据的正确性进行了测试。试验表明，该系统性能稳定，具有较强的抗干扰能力，有较强的实用价值。 关键词：无线通信 无线数据传输模块 单片机 射频 The system of wireless transceiver Abstract：With the rapid development of modern electronic technologies, communications technology has made considerable progress. In the field of wireless communications, more and more communications products emerge. However, the design of wireless data communication products often require considerable wireless expertise and high professional specialized equipment, thereby affecting users use and the new product development. nRF401 is the 433MHz ISM frequency band design wireless transceivers chip, for short-distance wireless data communication applications provide a better solution, using nRF401 reduced development difficulty, and shortened the development cycle, so that the products can be faster to the market. This article proposes one kind of the designs which applies to the wireless data transceiver system and a realizable plan. And the design methodology of the wireless data communication module is given based on the single chip microcomputer of AT89S52 and wireless radio frequency chip nRF401, analyses each part of the realization of the principle in detail, and test is conducted for the transmitted distance and correctness of data transmission of the system. The experimentation proves that the system has the characteristics of steady performance and strong anti-jamming ability, it has a stronger practical value.
