Abstract :
A power amplifier linearisation scheme using RF feedback is proposed. Stability compensation is provided using Cartesian baseband circuits. The method incorporates all the signal processing elements in the forward loop of the system as a means of eliminating nonlinear errors and noise introduced by the modulator/demodulator circuits
