本文介绍了一种V波段有源1：4功分器，采用90 nm LP CMOS工艺，用于相控阵发射机。该功分器在57 ~ 65 GHz频率范围内，每条RF通道的增益均优于0 dB，增益不平衡度为0.75 dB，相位不平衡度为4.3°。在2 V电源电压下，60 GHz时，两个相邻输出端口之间的隔离度优于15.2 dB，OP 1dB优于-2.67 dBm，直流功耗为40 mW。
This paper presents a V-band active one-to-four power splitter in 90-nm LP CMOS process for phased-array transmitter. This power splitter demonstrates a gain which is better than 0 dB from 57 to 65 GHz for each RF path. Besides, 0.75-dB gain imbalance and 4.3° phase imbalance are achieved. The isolation between two adjacent output ports is better than 15.2 dB, and the measured OP1dB is better than −2.67 dBm at 60 GHz while the dc power consumption is 40 mW with 2-V supply voltage.
