Abstract
A power amplifier chassis for an n+1 redundant power amplifier system. The power amplifier chassis includes an embedded controller and a power amplifier. The embedded controller operates the power amplifier chassis in a master controller mode or a slave controller mode. When operated in the master controller mode, the embedded controller monitors operating parameters associated with the power amplifier chassis, and can transfer control of the power amplifier system when the embedded controller senses that the monitored operating parameters indicate a failure or impending failure of the power amplifier chassis. When operated in the slave controller mode, the embedded controller receives control instructions from the master controller power amplifier module, and is enabled to reconfigure the power amplifier chassis from the slave controller mode to the master controller mode in response to a failure or imminent failure indication of a first power amplifier chassis operated in master controller mode.
