Patent ID: 7907014

Claim:
A system for dynamic adjustment of drain or collector voltage of a power amplifier, the system comprising: a power amplifier having a drain or collector voltage input; a power sensor configured to measure output power of the power amplifier; an adaptive power amplifier control processor configured to dynamically change a drain or collector voltage applied to the input of the power amplifier as a function of output power of the power amplifier measured by the power sensor to achieve a desired peak power when the system is subjected to larger than normal radio frequency (RF) output power; and a power amplifier amplitude to amplitude (AA) monitor configured to digitally analyze a transmit amplitude of the power amplifier to a receive amplitude of the power amplifier to determine output signal compression of the power amplifier, wherein the adaptive power amplifier control processor is configured to dynamically change the drain or collector voltage applied to the input of the power amplifier as a function of the determined output signal compression.
