Abstract
An ultra-wideband mixer using standard complementary metal oxide semiconductor (CMOS) technology was first proposed in this paper. This broadband mixer achieves measured conversion gain of 11 /spl plusmn/ 1.5 dB with a bandwidth of 0.3 to 25 GHz. The mixer was fabricated in a commercial 0.18-μm CMOS technology and demonstrated the highest frequency and bandwidth of operation. It also presented better gain-bandwidth-product performance compared with that of GaAs-based HBT technologies. The chip area is 0.8 × 1 mm 2 .
