摘要

介绍了一种采用0.25µm SiGe∶C工艺制作的高输出1dB压缩点60ghz上变频混频器。它以吉尔伯特单元为基础，结合本振无源堆叠马尔尚平衡将本振单端信号转换成差分信号。它采用由螺旋电感和MIM电容组成的调谐负载将差分输出匹配到100欧姆，并在频带中间衰减15 dB的图像信号。转换增益在61ghz频段为2.2 dB，在9ghz频段变化在2db以内，输出1db压缩点为−3.4 dBm。据我们所知，它是硅基60 ghz混频器中最高输出1 db压缩点。它从3.3 V电源消耗10 mA

A 60 GHz wideband high output P1dB up-conversion image rejection mixer in 0.25 µm SiGe technology

A high output 1dB compression point 60-GHz up-conversion mixer fabricated on 0.25 µm SiGe∶C technology is presented. It is based on the Gilbert cell and integrated with LO passive stacked Marchand balun to convert the LO single ended signal into differential. It employs tuned load consisting of spiral inductor and MIM capacitor to match the differential output to 100 ohm and to attenuate the image signal by 15 dB in the middle of the band. The conversion gain is 2.2-dB in 61 GHz and varies within 2 dB over 9 GHz band We achieve output 1-dB compression point of −3.4 dBm. To the best of our knowledge it is the highest output 1-dB compression point in silicon-based 60-GHz mixers. It consumes 10 mA from 3.3 V supply
