    3. THEORY OF OPERATION INTRODUCTION The Model 1000W1000H RF amplifier consists of a Pre-Amplifier, 2-Way Splitter, (1) Dual W-Module (10051104) used as driver amplifier, (2) 8-way Splitters, (6) Dual W-Modules (10054117) used as final amplifiers, (1) 12-way Combiner and a Directional Coupler assembly.

  • Page 68: A3 Driver Amplifier

    Model 1000W1000H 3.2.3 A3 Driver Amplifier 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 = +23V, with a VDD draw of 20.5 amps (10.2 per channel) and VGG draw below 0.15 amps.
