  • Method of adjusting gain and current consumption of a power amplifier circuit while maintaining linearity
    Patent number: 6646510
    Abstract: The gain and current consumption of a power amplifier are adjusted while maintaining amplified output signal linearity. Where linearity and low power consumption are maintained for the amplifier by controllable shunting of an input signal amplitude and by providing a predetermined bias signal to the amplifier circuit in a precalibrated manner. A mapping circuit is disposed for receiving a control signal and for providing the predetermined bias signal to the amplifier circuit in the precalibrated manner. The mapping circuit is either internally provided within the same circuit as the power amplifier, or externally.
