Abstract
The linear amplification using nonlinear components (LINC) technique is a well-known power amplifier linearization method to reduce adjacent channel interference in a nonconstant envelope modulation system. Its major drawback is the inherited sensitivity to gain and phase imbalances between the two amplifier branches. This work describes a method to correct gain and phase imbalances in LINC transmitters. The proposed method is based on genetic algorithms and it obtains a suitable solution for complex coefficients to adjust gain and phase imbalances. The method functionality has been verified by means of simulation
