Abstract
A modular power amplifier system includes power amplifier modules removably mounted within a cabinet. Each of the power amplifier modules includes an embedded controller and a power amplifier. An RF distribution panel includes an input port for receiving an RF input signal, and a signal splitter for dividing the RF input signal for input to the plurality of power amplifier modules. Coaxial dividers are configured to divide the RF input signal substantially equally between the plurality of power amplifier modules. Passive waveguide combiners are configured to combine the amplified RF output signals from the plurality of power amplifier modules at an output port to provide an RF output signal. A designated master controller monitors operating parameters associated with each power amplifier module. The combined power rating of the power amplifier modules exceeds a rated power of the system by at least one power amplifier module.
