提出了一种适用于低功耗无线通信系统的正交上变频混频器。该电路基于带有反射负载的六端口结来调制190 GHz的载波信号。虽然之前发布的大多数六端口上转换混频器都是在陶瓷衬底上制造的，并且使用分立的III-V半导体作为反射负载，但该电路使用了在单个芯片上集成六端口结的公共基级。该电路采用SiGe BiCMOS工艺制作，本振功率为-10.3 dBm，直流功率为36.5 mW，转换增益为-3 dB。基带中- 3db带宽为17ghz。据作者所知，这是在毫米波频率下工作的集成六端口上转换混频器的第一次演示。
A quadrature up-conversion mixer for low-power wireless communication systems is presented. The circuit is based on a six-port junction with reflective loads to modulate a carrier signal at 190 GHz. While most of the previously published six-port up-conversion mixers were fabricated on ceramic substrates and use discrete III–V semiconductors as reflective loads, this circuit uses common-base stages integrated with the six-port junction on a single chip. The circuit was fabricated in a SiGe BiCMOS process and a conversion gain of –3 dB is measured with –10.3 dBm of power from a local oscillator and 36.5 mW of dc power. The –3 dB bandwidth in the baseband is 17 GHz. To the best knowledge of the authors, this is the first demonstration of an integrated six-port up-conversion mixer operating at mm-wave frequencies.
