Abstract
A quadrature out-phasing system comprising: a first baseband signal modifier () arranged to receive a first baseband signal component () and output a first constant envelope RF carrier () and a second constant envelope RF carrier (); and a second baseband signal modifier () arranged to receive a second baseband signal component () and output a third constant envelope RF carrier () and a fourth constant envelope RF carrier (). The system may further comprise: a first signal combiner () arranged to combine the first constant envelope RF carrier () and the second constant envelope RF carrier (), and arranged to output a first RF PWM signal (); and a second signal combiner () arranged to combine the third constant envelope RF carrier () and the fourth constant envelope RF carrier (), and arranged to output a second RF PWM signal ().
