  • Broadband linearization module and method
    Patent number: 8736365
    Abstract: A system including a power amplifier and a pre-distortion module coupled to the power amplifier. The pre-distortion module includes one or more smaller versions of the power amplifier to generate a pre-distortion signal that compensates for any memory-effect or inertia present in the power amplifier with application on frequency hopping and larger (up to 1 octave) instantaneous bandwidth communication systems.
    Type: Grant
    Filed: October 31, 2011
    Date of Patent: May 27, 2014
    Assignee: Empower RF Systems, Inc.
    Inventors: Paulo Correa, Andre A. Castro
