ABSTRACT:
A power amplifier (power amplifier) having multiple solid state sub-amplifiers connected in parallel between the power amplifier input and the power amplifier output are described. The signal input to the power amplifier is provided to an RF splitter connected between the power amplifier input connector and the input of each of the sub-amplifiers The RF splitter splits the input power from the signal input and provides the power to the sub-amplifier inputs through input electrical paths. The input electrical paths from the power amplifier input to the sub-amplifiers are substantially physically identical. Each of the sub-amplifiers drive an input of an RF combiner connected between the outputs of the sub-amplifiers and the output of the power amplifier. The RF combiner combines the output power from each of the sub-amplifiers through output electrical paths, and provides the combined power to the power amplifier output. The output electrical paths from the sub-amplifiers to the power amplifier output are substantially physically identical.
