| Zusammenfassung: | The present invention provides a radio frequency power amplifier system (100) including a main power amplifier (101), having an input (107) and an output (108), a secondary power amplifier (102), having an input (109) and an output (110), an internal load (103) connected to the output of the secondary power amplifier, and a feedback network (104) having an input end connected to the output of the secondary power amplifier, and an output end connected to the input of the secondary power amplifier. The main power amplifier is a scaled up replica of the secondary power amplifier. The inputs of the main and secondary power amplifiers are interconnected at a common input node (113), and the power amplifier system has an input port (114) connected to the common input node. |
