Abstract
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 2 GHz, is proposed. The simulation and the implementation of the calibration were performed using the Agilent - ADS software.
