An exemplary transceiver comprises a power amplifier configured to receive a source signal and generate an amplified output signal, an antenna coupled to the power amplifier, the antenna being configured to radiate the amplified output signal, and a controller coupled to the power amplifier. The controller is configured to control an effective gain of the power amplifier based on a power level of operation of the transmitter. A source amplifier configured to operate on the source signal prior to power amplification is also controlled by the controller. The controller configures the gain level of the source amplifier based on the power level of operation of the transmitter and the effective gain of the power amplifier to improve signal-to-noise ratio.
