基于STM32F103的433MHz频段无线数传模块的设计

摘要

本文设计了一种可工作在433.00-434.79MHz，中心频率为433.00MHz，输出功率可调的无线数传模块。模块采用STM32F103RB单片机和射频芯片CC1101设计，利用EDA软件ADS2008仿真优化了射频电路的输出匹配网络。最后对无线模块输出功率，通信距离等参数进行了测试和验证。%This paper designed a wireless data transmission module working on 433.00MHz-434.79MHz (the center frequency of 433.00MHz), whose output power is adjustable. STM32F103RB microcontroller and RF module CC1101 chip are applied in this design. And the simulation is done by using EDA software ADS2008 to optimize the ouput matching network of the RF circuit. Finally, the wireless module output power, communication range and other parameters were tested and verified.
