Abstract :
This paper presents a new adaptive digital predistortion linearization technique and algorithm for high linearity RF power amplifier used for transmitters of IMT-2000 band mobile communication base station. Simulation results show an improvement of -63 dB for the third-order intermodulation distortion suppression. This technique is easy to realize adaptive control and suitable for circuit integration.
