Gain control apparatus, and an associated method, for a radio transmitter, such as the radio transmitter forming a portion of a mobile station. Gain control is effectuated by controlling the level of bias current at which a power amplifier is biased. Signals to be transmitted by the radio transmitter are also applied to the power amplifier to be amplified thereat. Because the gain of a power amplifier is directly proportional to the bias level at which the amplifier is biased, gain control is effectuated through control of the bias current by which the power amplifier is biased.
