Abstract

A 28GHz phased array transceiver with RF/IF conversion in 28nm bulk CMOS supports up to 12 antenna elements each on 2 MIMO layers. The transceiver is targeted for small antenna arrays in mobile user equipment, implements an AMPM compensated PA, passive 3b phase shifters and supports tiling to extend the antenna array size for prototype basestation applications. Radiated results are presented for both UE and basestation size arrays.
用于5G原型用户设备和基站的28nm批量CMOS 28GHz相控阵收发器
28GHz相控阵收发器采用28nm大块CMOS进行RF/IF转换,在2个MIMO层上支持多达12个天线元件。该收发器针对移动用户设备中的小型天线阵列,实现了AMPM补偿的PA,无源3b移相器,并支持平铺,以扩展原型基站应用的天线阵列尺寸。给出了UE和基站尺寸阵列的辐射结果。
