Abstract

In this paper, a new carrier complex power series for linearizing the distortion effects of a HPA (High Power Amplifier) is proposed. Amplitude (AM-to-AM) and phase(AM-to-PM) nonlinear characteristics of HPA are combined to generate carrier complex power series. Inverse carrier complex power series of predistortor is also proposed. The fabricated HPA of IMT- 2000 band with a measured gain and P1dB are 34.06dB and 35.4dBm. With proposed series, C/I (Carrier to Intermodulation) ratio of HPA is improved by 17.01dB(@Pout = 25.43dBm/tone) with 2-tone at 2.1375GHz and 2.1425GHz.
