摘　　要：直接降频转换接收器架构能够以较低成本提高无线系统基站接收器的性能。本文简要分析了超外差式接收器在无线基站接收器应用中的局限,介绍了TRF3710高线性正交解调器的主要功能以及使用增益控制、DC偏移校准方法,详细给出了基于TRF3710高线性、高集成度优势的直接降频转换接收器设计方案。Framework of direct-down conversion receiver can provide upper performance with lower cost for wireless base receiver. In this paper, the limitation of super-heterodyne receiver for wireless base receiver is briefly analyzed. The main function of TRF3710 highly linear quadrature demodulator and the means of gain control and DC offset calibration is introduced. And finally a design of direct-down conversion receiver that based on TRF3710 highly linear and integrated demodulator is given.
