Abstract: A control portion for controlling an amplifier portion of a transmitter device is provided. The amplifier portion is arranged to amplify a radio signal with a transmission gain based at least partially on a gain control signal and having a nominal gain relationship between the gain control signal and the transmission gain. The control portion is arranged to determine a desired transmission gain, to determine one or more operating conditions, to calculate a gain control signal for causing the amplifier portion to apply the desired transmission gain, taking into account the nominal gain relationship and the one or more operating conditions, and to output said gain control signal. The gain control signal is different to a gain control signal calculated based only on the nominal gain relationship.
