摘要: In this article, a 40-GHz subharmonic Gilbert down-conversion mixer with an accurate quadrature local oscillator (LO) input is demonstrated using a standard 0.13-mu m CMOS technology. The quadrature-output frequency divider is realized by injection-locked oscillators and is used at the LO port to replace conventional RC-CR polyphase filters at higher frequencies. Furthermore, the proper Marchand balun at all RF stage is suitable for the standard Si-based process to generate precisely balanced signals despite the substrate loss. The measured conversion gat In is 4 dB at 40 GHz. The IP(1dB) IIP(3) of - 7 dBm and 2 dBm, respectively, tire achieved. The measured 3-dB RF bandwidth is very broad and about 12-GHz bandwidth when the 10-MHz IF frequency is fixed. The die Size is about I mm X I mm. (C) 2009 Wiley Periodicals, Inc.
