    This paper presents a wideband GaN Doherty power amplifier (DPA) in the 2.6 GHz band with a 3 stages Wilkinson splitter where the impedance inverter is based on a tapered line instead of a quarter wave transformer. From ...
  • A wideband Doherty-like architecture using a Klopfenstein taper for load modulation 

    Bertran Albertí, Eduardo; Mehran, Yahyavi (2015-11-02)
    Open Access
    A novel Doherty-like power amplifier (DPA) has been fabricated using 15 W, 2.7 GHz, GaN HEMT transistors. The quarter-wave transformer used in the classical DPA topology is replaced by a matching network including a ...
