Abstract

The small-cell base station requires a high linearity, high reliable and high efficiency power amplifier to enhance signal strength in a coverage region. To meet the demand, the 2.6 GHz two-way symmetrical Doherty power amplifier module which uses modularized components, enhances system stability and integrates with heat sink is proposed. The experimental results show that the proposed module delivers a power-added efficiency of 27%, a gain of 47 dB, and adjacent channel leakage ratio of below -33 dBc at an average power of 40 dBm without non-linearity compensation for the LTE signal. Finally, the model of AM-AM and AM-PM with memory effects are predicted by measurement results and it can be used to improve the linearity of the proposed power amplifier.
