  • Compensating for a radio frequency amplifier
    Patent number: 8750416
    Abstract: An analog radio frequency input and an analog feedback from an output of a radio frequency amplifier are digitized and down-converted. Pre-distortion coefficients are calculated based on the down-converted input and down-converted feedback and the down-converted input is filtered using the pre-distortion coefficients. The filter output is then up-converted to a carrier frequency and converted to analog to be provided to the radio frequency amplifier.
    Type: Grant

    Assignee: Broadcast Electronics
    Inventors: Brian Lindemann, Doug Foote, Dan Prysby, John Ribe, David Kroeger
