To compensate the heavy path loss and increase the communications capacity, phased array beamforming and massive multiple-input multiple-output(MIMO) techniques are employed at both the user equipment(UE) and base stations(BS). Considering the commercial requirements, 5 G mm Wave large array systems should be implemented in an energy-and cost-efficient way with a small form factor. To address above issues and realize a reliable communications link, taking into account the particular characteristics of5 G mm Wave systems, this paper firstly examines the design challenges and trade-offs in system implementations, then some of the design strategies are summarized. At last, recent advance in RF front-end circuits and receiver sub-systems is then highlighted. 关键词：无线通讯在系统用户设备成本效率通讯连接检验设计设计策略接收装置
