ABSTRACT:
A novel transmitter circuit is disclosed for receiving of an input signal and for providing of an amplitude increased RF output signal. Pluralities of switching power amplifiers are disposed along two signal propagating circuit branches and utilized for increasing a magnitude of the input signal, to form an output signal, which is a magnitude increased version of the input signal. Each of the switching power amplifiers utilizes switching elements having various magnitude increasing capacity and coupled to a control circuit for each being switchably selectable for providing of the magnitude increase to the input signal.
