Abstract

A modular broadband transmission system and method include an input signal connector that receives an input signal which is then divided into N parts and amplified with an amplifier have N power amplifier modules. Outputs of the N power amplifier modules are passed through transmission lines and to a radial combiner that combines the outputs. The radial combiner, transmission lines and power amplifier modules are configured such that if one of the power amplifier modules fails, the other power amplifier modules may still operate acceptable well, with minimal impact on total output power. An output of the amplifier is provided to a coupler that measures a power level of the output signal and feeds the measured power level back to a controller where the controller adjust an overall output power based on the number of the power amplifier modules that are functioning properly. Each of the power amplifier modules have a processor such that respective of the power amplifier modules may be taken off-line, and replaced while the other power amplifier modules continue to operate in a transmit mode of operation. The modular broadband transmission system and method may conveniently be used as either a broadband booster for amplifying a plurality of input signals, or a head and transmitter configured to amplify one or more different input signals.
