Abstract
A distributed power converter is for use with an RF power amplifier and includes a primary converter connected to an input voltage and configured to provide a regulated DC intermediate voltage that is galvanically isolated from the input voltage. Additionally, the distributed power converter also includes a secondary regulator connected galvanically to the regulated DC intermediate voltage and configured to generate a regulated DC supply voltage for at least a portion of the RF power amplifier. In another aspect, a method of operating a distributed power converter is for use with an RF power amplifier and includes providing a regulated DC intermediate voltage that is galvanically isolated from an input voltage and generating a regulated DC supply voltage for at least a portion of the RF power amplifier that is galvanically connected to the regulated DC intermediate voltage.
