Abstract (en)
[origin: WO2006088604A2] An amplifier system is provided that has a first balun with an input and an output, and a second balun with an input and an output. A first set of amplifiers is coupled in series and to the output of the first balun. A second set of amplifiers is coupled in series and to the output of the second balun. The first and second sets of amplifiers are in series or parallel. A load impedance of the first and second sets of amplifiers does not substantially change at an output of any amplifier that is switched on when another amplifier is switched off.
