Abstract :
This paper presents a 1.5 V, full CMOS, quadrature, direct upconversion mixer for multi-mode wireless communications. The chip includes both a wide band polyphase filter, the linear quadrature up-conversion mixers and a single-ended output stage. More than 35 dBc mirror suppression has been measured over the 700 MHz to 3 GHz frequency range, without any additional trimming or tuning. Any distortion or intermodulation component is lower than -32 dBc and the LO feedthrough is below -35 dBc up to 3 GHz. The chip has been realized in standard 0.25 μm CMOS technology
