    3. THEORY OF OPERATION INTRODUCTION The Model 3000W1000B RF amplifier consists of a driver amplifier assembly, six 500 watt power amplifier assemblies, four 12-way combiners, a 4-way combiner and a directional coupler. The driver amplifier amplifies low level RF signals and provides RF signals that are matched in amplitude and phase to the 500 watt amplifiers.
