Abstract In this paper, a novel analysis of feedforward linearizing power amplifier is presented. Experimental results are reported for a CDMA IS-95 base station feedforward linearizing amplifier, which demonstrates a minimum of 23dB intermodulation distortion suppression when the amplifier s gain is 47 dB and continue wave output power is 60W.

Key words： Feedforward linearizing CDMA Linear power amplifier Intermodulation
