ABSTRACT:
A method of linearizing an amplifier having an input and an output involves the steps of amplifying the amplifier input signal with a vector modulator having a gain adjustment signal input for receiving a gain adjustment signal and adjusting the gain of the vector modulator in response to a gain adjustment signal to produce an amplifier output signal at the amplifier output. This is followed by producing a gain error signal dependent upon the amplifier input signal and the amplifier output signal, the gain error signal having real and imaginary components lying within pre-defined regions in a complex plane. Finally, the gain adjustment signal is generated in response to a region in the complex plane in which an error signal vector defined by the real an imaginary components of the error signal vector lies.
