Abstract :
A LINC transmitter exhibits memoryless amplitude dependent distortion characteristics when gain/phase imbalances are present between the two amplifier branches. Simulation results show that using a complex gain predistorter can correct for the gain/phase imbalances and significantly reduce interference in adjacent channels
