摘要

在本文中，我们提出了使用直接射频欠采样接收机在高shf (6GHz以上)频段进行数字波束形成。直接射频配置可以减少每个天线单元附加的单个接收器的尺寸，并可以实现适用于5G系统中大规模多输入多输出(MIMO)的数字波束形成功能。介绍了高高频带直接射频欠采样S/H CMOS集成电路的最新进展。

Direct RF undersampling receiver for high-SHF band digital beam forming

In this paper, we proposes the usage of direct RF undersampling receiver for digital beam forming in high-SHF (over 6GHz) band. The direct RF configuration can be reduce the size of individual receiver attached to each antenna elements and can be realize digital beam forming functionality which is applicable to Massive Multiple-Input-Multiple-Output (MIMO) in 5G system. Recent development of direct RF undersampling S/H CMOS IC in high-SHF band is also introduced.
