Abstract
A method for controlling a supply voltage for a radio frequency power amplifier, that includes the steps of: determining (210) at least one parameter; determining (220) a constant voltage based on the at least one parameter; and automatically adjusting (230) the supply voltage to the constant voltage.
Claims19
A method for controlling a supply voltage for a radio frequency power amplifier (PA), comprising the steps of:
- determining a power ratio, wherein the power ratio is a percentage utilization of a peak power capability of the PA;
- determining a constant voltage based on the power ratio using a predetermined function;
- and
- automatically adjusting the supply voltage to the constant voltage.
