  • Power minimization, correlation-based closed loop for controlling predistorter and vector modulator feeding RF power amplifier
    Publication number: 20040021517
    Abstract: An RF power amplifier linearizer uses a switched distortion power-minimization routine, or simultaneous correlation and power-minimization routines to adjust operational parameters of a vector modulator and a predistortion operator feeding the RF amplifier. The switched power-minimization routine controls the vector modulator, and then adjusts coefficients of the predistorter using the same power minimization routine. The continuous correlation and power minimization routine adjusts the predistortion unit by means of a power minimization unit, and uses a correlator based control mechanism to control the vector modulator simultaneously with the power minimization routine's control of the predistortion unit.
