ABSTRACT:
An RF power amplifier control system is presented herein. The system includes a group of power amplifier modules for amplifying an RF signal. Each group includes first and second group controllers for, when on, controlling the operation of the power amplifier modules including turning on and turning off each of the modules within the group. The first group controller is normally on for controlling the amplifier operation and the second group controller is turned on for controlling the operation only when the first controller is turned off. First and second central controllers are provided for, when on, controlling the operation of the first and second group controllers. The first central controller is normally on to provide the control operation and the second central controller monitors the operation of the first controller and performs the control operation in the event that the first central controller malfunctions.
