Abstract: A system and method for managing and controlling a transmit power of a transmitter of a RF transmission system are disclosed. When the transmitter operates from a constrained supply like a generator or battery, power draw may limit the output that can be supported by the transmitter or result in a shutdown of the entire system. The system includes a plurality of detection and measurement circuitries to detect parameters relative to the transmitter load quality, transmitter temperatures, input waveform quality, and input power source to ensure an output power of the transmitter to stay below an allowed input power. The system and method provide a reliable transmitter that is not subject to power overloads and shutdowns caused by a circuit malfunction.
