  • Inverted Doherty power amplifier with large RF and instantaneous bandwidths
    Patent number: 11843352
    Abstract: Apparatus and methods for an inverted Doherty amplifier operating at gigahertz frequencies are described. RF fractional bandwidth and signal bandwidth may be increased over a conventional Doherty amplifier configuration when impedance-matching components and an impedance inverter in an output network of the inverted Doherty amplifier are designed based on characteristics of the main and peaking amplifier and asymmetry factor of the amplifier.
    Type: Grant
    Filed: June 17, 2021
    Date of Patent: December 12, 2023
    Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.
    Inventors: Christian Cassou, Gerard Bouisse
