Abstract: According to the method and apparatus of the present disclosure, dual drain control uses a variable voltage supply on the drains of a first stage (302) and a second stage (304) to control the output power. In particular, dual drain control having a 1:1 ratio is employed at lower power levels, with single drain control at higher power levels. Such drain control could be employed by directly varying (1008, 1010) the voltage on the drains of the power amplifier, such as with signals from a microprocessor, or by a specific circuit (203) to generate the drain voltages based upon a control voltage.
