At present,the wireless communication technology is developed rapidly,which causes the demands of the low-power consumption system. In recent years, the low-power consumption technology in wireless communication network are stu-died deeply,so energy conservation has become an important direction of the wireless communication development. The design of low-power wireless transceiver circuit system is carried out in this paper,in which STM32L151 series ultra low pow-er chip and UTC4432 series wireless communication module are taken as the core circuit system to realize the function of the low power transceiver circuit system through software design and debugging. The results show that the suitable micro control-ler and wireless communication module are important for the the power consumption control of wireless transceiver circuit sys-tem. Together with the software programming control,the power consumption of the whole system can be reduced greatly.%目前，无线通信技术发展极其迅速，随之引起系统功耗不断上升。因此人们近几年来对无线通信网络中各方面的低功耗技术进行了深入的研究，使节能成为无线通信发展的一个重要方向。设计了低功耗无线收发电路系统，采用STM32L151系列超低功耗芯片和UTC4432系列无线通信模块作为核心电路系统，通过软件设计及调试实现整个低功耗收发电路系统功能。结果表明：采用合适的微控制器和无线通信模块对于控制无线收发电路系统的功耗有着极其重要的作用，再加上对软件编程的控制，能够使整个系统的功耗大幅度降低。
