Patent ID: 8320850

Claim:
A method comprising: providing a first radio frequency (RF) terminal comprising an RF receiver, an RF power amplifier, and a tunable antenna matching circuit, such that the tunable antenna matching circuit is coupled between an output of the RF power amplifier and an antenna; receiving at least a first command from a second RF terminal using the RF receiver, such that the at least the first command instructs the first RF terminal to adjust an output power from the first RF terminal; adjusting an impedance of the tunable antenna matching circuit and adjusting at least one input signal to the RF power amplifier in response to the at least the first command; detecting a phase shift of an RF transmit signal from the first RF terminal resulting from adjusting impedance of the tunable antenna matching circuit; and applying a compensating phase shift to an input signal to the RF power amplifier based on the detected phase shift, wherein the output power is based on the impedance of the tunable antenna matching circuit and the at least one input signal to the RF power amplifier.
