An integrated circuit includes an RF transmitter that transmits a transmit signal at a selectable transmit power to a base station in accordance with a wireless telephony protocol, based on a transmit power control signal. An RF receiver receives a received signal from the base station in accordance with the wireless telephony protocol, and generates a feedback signal based on either a protocol parameter of the wireless telephony protocol or a position signal. A processing module generates the transmit power control signal based on the feedback signal, and generates a power mode signal for adjusting transmitter power supply parameters, based on the transmit power control signal.
