1. A method for controlling a circuit within a transmitter, the method comprising:

  • adjusting a gain of at least one of a plurality of gain stages in an RF transmit path based on a control signal that is indicative of a measured battery voltage, wherein said gain is adjusted based on a voltage range that enables configuration of each of said at least one of said plurality of gain stages to meet performance requirements,wherein adjusting the gain comprises increasing the gain of at least one of the plurality of gain stages responsive to the measured battery voltage being higher than a designed voltage corresponding to the plurality of gain stages.
