Abstract: Disclosed is an RF transmitter circuit (10), as well as a method for operating the circuit. The RF transmitter circuit includes a VGA (20), that includes circuitry for generating a feedback signal, and a temperature compensation block (18) having an input coupled to a gain control signal and an output coupled to an input of the VGA for providing to the VGA a compensated gain control signal. The temperature compensation block further includes a bias input that receives the VGA feedback signal. The VGA feedback signal operates to modify the gain control signal to reduce an amount of variability in a VGA gain slope over a range of VGA output power.
