摘　　要：新的软件无线电技术(Software Defined Radio,SDR)平台正在向宽带、多模和多频段(Multi-band Radio,MBR)演进,相应MBR技术研究日益重要。针对MBR基站宽带接收机的设计进行了分析和研究。分析了MBR基站宽带接收机设计所面临的技术挑战,给出了基于直接下变频技术的MBR基站宽带接收机实现架构,对于直接下变频技术应用的技术要点进行了探讨和分析,并给出了一个具体设计实例。The new software defined radio（SDR） platform is evolving to wideband, multimode and multiband radio（MBR）. The MBR technology research is increasingly important. In this paper,the design of wideband receiver for MBR base station is analyzed and studied. The key technologies and challenges about wideband receiver for MBR base station are analyzed. Based on the direct down conversion technology,a realization architecture of wideband receiver for MBR base station is presented. The key technical points of direct down conversion receiver are discussed and analyzed,and a specific design example is given.
