目前，移动/游牧卫星通信终端越来越受欢迎，特别是对不断扩大的K/ ka波段业务。本文将概述使用rf移相器件的经典相控阵rf前端与在数字电平处理天线元件信号的数字波束形成拓扑之间的权衡。IMST及其合作伙伴开发的射频前端将作为这两种拓扑结构的说明。
Nowadays, mobile/nomadic satcom terminals are becoming more and more popular, especially for the expanding K/Ka-band services. This paper will give an overview of tradeoffs between the classical phased array RF-frontends where RF-phase shifting devices are used, and digital beam forming topologies where the antenna elements signals are handled at digital level. RF-frontends developed by IMST and partners will serve as illustration of both topologies.
