Patent ID: 7937049

Claim:
A transmitter system for transmitting an input signal represented by an amplitude modulation component and a phase modulation component, comprising: a predistortion module, the predistortion module producing a control voltage by applying predistortion to a signal responsive to a corrected signal and the amplitude modulation component; a power amplifier driving a load impedance with an amplified signal; a power control/current detection circuit, the power control/current detection circuit supplying a supply voltage and a supply current to the power amplifier in response to the control voltage and producing a signal indicating the supply current drawn by the power amplifier to produce the amplified signal; and a power correction module, the power correction module producing the corrected signal in response to the signal indicating supply current drawn by the power amplifier; wherein said power control/current detection circuit uses the control voltage to correct said supply voltage in response to a change in said load impedance.
