3.  THEORY OF OPERATION 

3.1  INTRODUCTION 

The Model 1000S1G6C RF amplifier consists of a 1–6 GHz RF amplifier assembly.  The RF amplifier assembly 

consists of a Pre-Amplifier (Pre-Amp), one (1) Quadrature-Coupled Amplifier (Quad Amp) used as a driver 

one (1) high power Quad amp, (5) 4-Way Splitter, (4) additional high power Quad amps, (16) high power Quad 

amp finals, (2) 8-way Combiners (1) 2-Way Combiner and Directional Coupler assembly. Reference Block 

Diag. 10052294 for breakdown of RF structure. 

The power supply section consists of an AC input, circuit breaker, filter, five switching power supplies, and a 

regulator circuit. 

The control system consists of a Control/Fault Board, an Interface Board and remote interfaces for IEEE-488, 

RS-232, USB, and Ethernet. 

Global fault monitoring and reporting is controlled through the front panel display. 

3.2  RF AMPLIFIER OPERATION 

3.2.1 

A1 Pre-Amp 

The Pre-Amp is assembled on PTFE composite printed wiring boards.  The RF input signal is fed to the A1 

Pre-Amp.  The pre-amp consists of a GaAs Attenuator, MMICs and a Wilkinson splitter.  The attenuator is used 

for manual gain control using the front panel gain control and to attenuate RF input signals above 0 dBm by 

utilizing internal voltages. 

U2 is a broadband GaAs Monolithic Microwave Integrated Circuit (MMIC) and is the first stage of gain in the 

amplifier. The output of U2 is fed to the input of the Wilkinson Two-Way Splitter. 

The Wilkinson Two-Way Splitter splits the signal into two paths.  One output is fed to the input of the A3 

Driver Amp and the other output is fed to a detector.  The detector output is used to protect the unit in the event 

of input overdrive. 

The output driver is fed to another MMIC to boost the gain.  Total gain is about 30dB. 

3.2.2 

A2 Driver Amp 

The Driver Amp is assembled on thin film substrates.  It has two (2) GaN amplifier sections.  Each section is 

input and output DC isolated by coupling capacitors.  A 90

˚

quad coupler combines the RF outputs.  50Ω

 

termination resistors absorb any difference signals and help to improve the input and output VSWR of the 

module.  The module has a gain of approximately 10dB and delivers 20 watts of RF power.  Active bias circuitry 

regulates the DC current through RF devices.  The nominal DC current for this amplifier is approximately 3.2A 

from a 24V supply.  Logic low voltage on the fault pin indicates a low or high current condition exists on GaN 

FET 1 (bottom) or FET 2 (top).
