Claim:
1. A power amplifier system, comprising: a first power amplifier unit to receive an input power signal and provide an output power signal, the output power signal having higher power than the input power signal; a power splitter unit to receive the output power signal from the first power amplifier unit and to generate a plurality of split power input signals, each of the plurality of split power input signals in-phase with one another; a second power amplifier unit to receive the plurality of split power input signals, each of the plurality of split power input signals in-phase with one another, the second power amplifier unit including a plurality of power amplifiers, each of the plurality of power amplifiers of the second power amplifier unit configured to receive one of the plurality of split power input signals and to provide one of a plurality of split power output signals; at least one isolator unit to couple at least one of the plurality of power amplifiers of the second power amplifier unit with a power combiner unit; and the power combiner unit to receive the plurality of split power output signals from the second power amplifier unit via the at least one isolator unit and to combine the plurality of split power output signals into a unified power output of at least 800 W and having a frequency of between 2.0 GHz and 3.0 GHz.
