摘　　要：简要介绍射频IC系统的结构,并针对现有射频IC系统接收电路的不足,通过调整混频器增益、混频管之间距离和工作频率等方法,实现对接收电路的优化。通过仿真,证明了优化的有效性。The first system of radio frequency IC briefly introduce the structure, according to the design of a protocol specification system to receive radio frequency IC circuit. RF IC system for the existing shortcomings of the interface circuit that the gain from the mixer, mixing tube and the distance between the frequency of job cut, the implementation of the interface circuit optimization. Finally, through simulation, demonstrated the effectiveness of optimization.
