摘要

本文提出了一个完整的2×2相控阵发射机系统,该系统工作在w波段(90-95 GHz),采用锁相环参考时移方法代替传统的毫米波移相器。锁相环参考移位使相控阵能够分布在多个芯片上,而不需要在芯片之间进行相干毫米波信号分布。所提出的相控阵发射系统在65纳米CMOS技术中实现时,每个阵列元件消耗248 mW。

A 2×2 W-band reference time-shifted phase-locked transmitter array in 65nm CMOS technology
This paper presents a complete 2×2 phased array transmitter system operating at W-band (90-95 GHz) which employs a PLL reference time-shifting approach instead of using traditional mm-wave phase shifters. PLL reference shifting enables a phased array to be distributed over multiple chips without the need for coherent mm-wave signal distribution between chips. The proposed phased array transmitter system consumes 248 mW per array element when implemented in a 65 nm CMOS technology.
