In this paper, an improved version of the digital calibration method for carrier leakage, which is caused by the DC offset on direct conversion transmitter, is proposed. We have used a power detector for estimating the DC offset. After, we have injected a compensation voltage for eliminating this DC offset. In order to validate our technique, a new direct conversion transmitter that operates at 2GHz, is proposed. The simulation and the implementation of the calibration were performed using the Agilent - ADS software.
