Abstract

To have both high efficiency and linearity in POWER AMPLIFIERs LINEARIZATION TECHNIQUES should be used. One structure with the ability of cancelling the inherent limitations of the LINC LINEARIZATION TECHNIQUES is proposed in this article. The gain and phase imbalances in LINC technique has been compensated using OPTIMIZATION ALGORITHMS. According to the analysis a feedback path has been added in the conventional LINC TRANSMITTER that calibrates any phase and gain mismatches adaptively; using OPTIMIZATION ALGORITHMS. Many simulations have been performed to validate the structure functionality and extracted relations. In this paper M68749 POWER AMPLIFIER is used at 390MHz frequency with output power of 5 watt. Simulations show that power spectral density of proposed architecture has 40dB/Hz improvement in spreading to adjacent channels.
