Gain control for communications device

Computer readable media embodying a method of controlling gain of an amplifier having a gain represented by one of a plurality of gain curves depending on a value of a parameter, the method comprising:

• storing a predetermined gain curve relating to the gain curve of the amplifier for a first one of the parameter values;
• adjusting a gain control signal corresponding to a point on the predetermined gain curve as a function of a second one of the parameter values;
• and
• applying the adjusted gain control signal to the amplifier.

An apparatus, comprising:

• a receiver having a gain represented by one of a plurality of receiver gain curves depending on a value of a receiver parameter;
• a transmitter having a gain represented by one of a plurality of transmitter gain curves depending on a value of a transmitter parameter;
• and
• a gain control configured to control the gain of the receiver from a predetermined receiver gain curve relating to the receiver gain curve of the receiver for a first one of the receiver parameter values by adjusting a receiver gain control signal corresponding to a point on the predetermined gain curve as a function of a second one of the receiver parameter values, and applying the adjusted receiver gain control signal to the receiver, the gain control further being configured to control the gain of the transmitter from a predetermined transmitter gain curve relating to the transmitter gain curve of the transmitter for a first one of the transmitter parameter values by adjusting a transmitter gain control signal corresponding to a point on the predetermined transmitter gain curve as a function of a second one of the transmitter parameter values, and applying the adjusted transmitter gain control signal to the transmitter.
