    3. THEORY OF OPERATION INTRODUCTION The Model 1000W1000G RF amplifier consists of a Pre-Amplifier and a driver amplifier, a 2-Way Splitter, two 8-Way Splitters, 16 Final Modules, a 16-way combiner, a directional coupler, and a detector assembly. The driver amplifier section amplifies low level RF signals and provides RF signals that are matched in amplitude and phase to the 16 Final modules.

    Model 1000W1000G 3.2.3 A2 Driver Amplifier (Schematic 10036697) The A2 driver amplifier consist of RF matching circuits, RF transistors, DC current control circuits, DC switching circuits and fault detection circuits. The RF input is fed to a 4:1 transformer composed of T1, T2, and T3. The push-pull output signal of the 4:1 transformer is connected to the gates of push-pull connected Q1.

    Model 1000W1000G The current through Q1 is monitored by U2. The output of U2 is fed to an op amp (U5) which has a reference voltage on the non-inverting input and it compares the output of U2 to the reference voltage and generates an error signal to vary the gate voltage of the RF transistor Q1 which controls the drain current.
