    3. THEORY OF OPERATION INTRODUCTION The Model 2000W1000E RF amplifier consists of a Pre-Amplifier, (2) Dual W-Modules used as driver amplifiers, (3) 8-way Splitters, (12) Dual W-Modules used as final amplifiers, (2) 12-way Combiners, a 2-way combiner, and a Directional Coupler assembly.

  • Page 66: A2, A4 Driver Amplifiers

    Model 2000W1000E 3.2.2 A2, A4 Driver Amplifiers The power module is a dual channel RF amplifier module structured around GaN FET dice arranged in a push- pull configuration. The module operates on a dual supply of VGG = -8V and VDD = +25V, with a VDD draw of 20.5 amps (10.2 per channel) and VGG draw below 0.15 amps.

  • Page 67: A20/21 12-Way Combiner

    Model 2000W1000E drain current fault may result from operating the amplifier beyond the prescribed load, drive, or modulation conditions, or as the result of compromised module components. If certain conditions generate a predictable fault, those operating conditions should be reviewed to verify they do not violate the safe operating parameters of the amplifier, such as a high peak power which may violate maximum allowable input power in any signal with high peak-to-average ratio.

  • Page 68: Control System

    Model 2000W1000E CONTROL SYSTEM 3.4.1 A36 ALC Board (Schematic 10023927) This section describes the operation of the level control board. The level control board performs the following functions: • Provides automatic level control of the amplifier’s output when the amplifier is placed in the ALC mode.

  • Page 69: Maintenance

    4. MAINTENANCE GENERAL MAINTENANCE INFORMATION Because it is a relatively simple instrument, the Model 2000W1000E requires very little maintenance. It is built with solid state devices and printed wiring boards (PWBs) that should ensure long, trouble-free life. Should trouble occur, special care must be taken when servicing the unit to avoid damaging solid state devices and PWB’s.
