Abstract:
1. An RF transceiver comprising: an RF receiver that receives a received signal from an external device, the RF receiver including: a processing module, coupled to the RF receiver, that generates a transmit power control signal based on the AGC signal, wherein the processing module filters the AGC signal to generate a filtered AGC signal that responds to slower changes in the AGC signal to avoid rapid fluctuations and wherein the processing module adjusts the transmit power control in response to the filtered AGC signal by comparing the filtered AGC signal to a corresponding plurality of transmit power control thresholds; and an RF transmitter, coupled to the processing module, that generates a transmit signal having a selected power level, wherein the selected power level is based on the transmit power control signal, wherein the RF transmitter includes at least one power amplifier that is capable of operating at one of a plurality of power levels, including the selected power level, and at least one power supply signal is adjustable to supply power to the at least one power amplifier based on the selected power level.
