N2 - In this paper we study various techniques of power RF amplifier linearization and analyze the most effective circuits of predistortion digital circuits. We propose a method for adapting this circuit and compare the advantages and disadvantages of this circuit with conventional predistortion circuit. The main problem with predisrortion circuit is the memory effect. We propose a new circuit to overcome the above problem based on digital signal processing techniques. Finally we compare results of our simulation with previous results. Our simulation shows an 8dB reductional in power ratio of adjacent channel.
