这项工作包括一个由4个移相器和天线组成的阵列,工作频率为60 GHz,用于波束形成系统。通过门构成了选相电路的开关核心,该选相电路被复制以构成矢量调制器移相器。对于16路系统,最终波束精度优于2度。芯片面积为2.7 mm×2.8 mm,1.2V电源电压下缓冲器电流为240 mA,通道门不耗电
This work comprises an array of 4 phase shifters and antennas operating at 60GHz for a beamforming system. Pass gates form the switching core for a phase selector circuit which is replicated to build up a vector modulator phase shifter. The final beam accuracy is better than 2deg for a 16-way system. The die area is 2.7mm times 2.8mm, the buffers take 240mA from a 1.2V supply, the pass gates take no power
