A 2-GHz carrier leakage calibrated direct-conversion WCDMA transmitter in 0.13-μm CMOS.

A highly integrated 2-GHz, 0.13-μm CMOS direct-conversion transmitter for wide-band code division multiple access (WCDMA) is described. Different circuit and calibration techniques are presented that successfully suppress the carrier leakage and enable the direct-upconversion architecture to meet al...
