Abstract
A method and system for modulating a drain supply voltage of a power amplifier are disclosed. A low pass envelope of a dual band modulated signal input to the power amplification system is determined. The determined low pass envelope is amplified. A drain supply of the power amplifier is modulated based on the amplified determined low pass envelope.
