Abstract
Methods and apparatus for providing gain control feedback in rf amplifiers in such transmitting devices as cell phones. In a cell phone application, the transmit level is set by the base station. In the cell phone, the transmit level received from the base station is used to select the coupler sensing the output power of the power amplifier in the cell phone, as well as to set the power amplifier gain. This allows the selection of couplers from multiple couplers to achieve the desired coupler output sensitivity and linearity for any part of the power amplifier output power range.
