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 an unregulated 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 unregulated 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 an unregulated 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 unregulated DC intermediate voltage.
