本文介绍了一种60 GHz单平衡式亚谐上变频器。该单片微波集成电路(MMIC)芯片采用标准的0.13微米混合信号/射频(RF)cmos工艺实现。该电路结合了一个次谐波混频器和一个三级共源共源共栅输出放大器。采用一种新型的小型变压器耦合器，为本振信号提供90°的相位差，实现亚谐混频。该MMIC在58~66 GHz的射频范围内具有5分贝的转换增益，2LO-RF隔离度超过40分贝。芯片尺寸仅为0.366 mm 2。
A 60 GHz singly balanced subharmonic up-converter is presented in this letter. The monolithic microwave integrated circuit (MMIC) chip is implemented using a standard 0.13 mu m mixed-signal/radio frequency (RF) CMOS process. This circuit combines a subharmonic mixer and a three-stage cascode output amplifier. A new miniature transformer coupler is used to provide the local oscillation (LO) signals with 90deg phase difference to achieve subharmonic mixing. This MMIC demonstrates a conversion gain of 5 dB for RF frequency from 58 to 66 GHz, and the 2LO-to-RF isolation is over 40 dB. The chip size is only 0.366 mm 2.
