Abstract: A transmitter has a transmission modulator including first and second modulators, a phase comparator and a controller. First and second non-inverted local signals supplied to the modulators are set to have a predetermined phase difference. In a calibration action for reducing carrier leakage, the phase comparator is supplied with the first or second local signals, and carrier signals leaking at an output of the transmission modulator. The controller keeps changing the ratio of DC biasing currents to paired transistors of each modulator until the predetermined phase difference is detected with the phase comparator. When the predetermined phase difference is detected, the controller stops changing the ratio of DC biasing currents. The chip footprint of a transmitter on the direct up-conversion (DUC) architecture is reduced, and carrier leakage owing to local signals supplied to the transmission modulator are decreased.
