Abstract :
This paper presents a low power double-quadrature down-conversion mixer for second stage down-conversion application in the 60 GHz receiver chain. The mixer utilizes double-balanced Gilbert-cell topology, and operates over a wide RF bandwidth of 7 GHz centered at 15 GHz, with a LO bandwidth of 4 GHz centered at 12.5 GHz. With low LO drive power requirement of -8dBm, the mixer realizes a conversion gain of 2 dB with a 1 dB flatness across an IF bandwidth of 2.9 GHz. It also has good spurious rejection of more than 40 dBc. The mixer consumes 7.11 mA from a 1.8 V supply, and is fabricated using Tower Jazz´s 0.18 μm SiGe BiCMOS process.
