Abstract:
A modular transmission system comprising:an input signal connector configured to be connected to a signal source and receive an input signal therefrom;a modular amplifier comprising,a divider circuit that divides said input signal into a plurality of divided signals, andN power amplifier modules, each configured to receive and amplify at least one of said divided signals and to provide a corresponding amplified output signal, N being an integer greater than or equal to two;a plurality of transmission lines, each having a first end coupled to a corresponding one of said N power amplifier modules and configured to couple respective amplified output signals therefrom, said plurality of transmission lines each having a second end;a radial combiner comprising N radial combiner input terminals coupled to respective of said second ends of said transmission lines, said radial combiner having an output connector through which an output signal is output within a predetermined output power level range; anda controller coupled to said amplifier and configured to keep said output signal within said predetermined output power level range, where said predetermined output power range is based on the number of the amplified output signals applied to said N radial combiner input terminals.
