The design of RF transceiver module with power amplifier based on CC1020

随着无线通信技术的发展,无线数传系统成为1个重要的发展方向。针对无线数传系统中单片射频收发芯片在远距离通信方面存在的不足,本文介绍了1种由CC1020无线收发芯片与功率放大器PA2460组成的射频收发系统模块设计方案。该模块具有低功耗、体积小的特点,并可方便地集成到各种无线测控系统中。本文详细阐述了设计思路并给出硬件电路与软件设计流程。实验结果表明,本文设计的模块有效地实现无线数传功能,发射功率达到30dBm,最远传输距离可达2 000m。

With the development of wireless communication technology,wireless data transmission system become an important aspect.In view of the disadvantage of the single-chip radio frequency（RF）transceiver of the wireless data transmission system which is not suited for long-distance transmission,the paper introduces a design proposal about RF transceiver module in wireless communication which is composed of a RF transceiver chip-CC1020 and a power amplifier-PA2460.The module has features of low power and small size and can be integrated into wireless measurement control system.The paper describes the design ideas and give the hardware circuit and software design process of the system.The practice result indicates that the module achieves the function of wireless data transmission and achieves the largest launch power up to 30 dBm and the farthest transmission distance up to 2 000 m.
