  • Linearization circuits and methods for multilevel power amplifier systems
    Patent number: 8829993
    Abstract: Circuits and methods for achieving high linearity, high efficiency power amplifiers, including digital predistortion (DPD) and pulse cancellation in switched-state RF power amplifier systems are described.
    Type: Grant
    Filed: March 15, 2013
    Date of Patent: September 9, 2014
    Assignee: Eta Devices, Inc.
    Inventors: Mark A. Briffa, Joel L. Dawson, John E. DeRoo, Krenar Komoni, David J. Perreault, Oguzhan Uyar
  • RF amplifier architecture and related techniques
    Patent number: 8824978
    Abstract: A radio frequency (RF) power amplifier system or transmitter includes one or more power amplifiers and a controller that is configured to adjust amplitudes and phases of RF input signals of the one or more power amplifiers and supply voltages applied to the one or more power amplifiers. In embodiments where multiple power amplifiers are used, a combiner may be provided to combine outputs of the power amplifiers. In at least one implementation, amplitude adjustment of the RF input signals of the one or more power amplifiers may be used to provide transmit power control and/or power backoff.
