GENERAL INFORMATION

1.1 GENERAL DESCRIPTION

The Model 100S1G6AB is a self-contained, Class AB broadband microwave amplifier designed for

laboratory applications where instantaneous bandwidth, high gain, and moderate power output are required.

GAIN

control, which is conveniently located on the unit’s front panel, can be used to decrease the

amplifier’s gain by 10 decibels (dB) or more. Solid state technology is used exclusively to offer significant

advantages in reliability and cost. A Model 100S1G6AB, used with a frequency-swept signal source, will

provide 100 watts of swept power output from 1.0–6 gigahertz (GHz). Typical applications include antenna

and component testing, wattmeter calibration, and electromagnetic interference (EMI) susceptibility testing,

as well as usage as a driver for frequency multipliers and high-power amplifiers. The Model 100S1G6AB can

be operated locally by using the unit’s front panel controls, or remotely by using the unit’s IEEE-488, RS-232

interface, USB, or Ethernet interface.

1.2 POWER SUPPLIES

The Model 100S1G6AB contains a switching power supply. The input voltage range to the power supply is

90–250 VAC, 50-60Hz, selected automatically.

PS1 is a multiple output supply. The main +28.0 volts DC supplies voltage to the RF low level and final

stages. The sec24 volts DC is for operating the cooling fans and the –24 volts DC is supplied to the

(A19) Regulator board. Primary AC circuit protection is provided by the AC fuses in the Power Entry

Module.

1.3 SPECIFICATIONS

Refer to the AR Data Sheet at the end of this section for detailed specifications. All voltage measurements

referenced in this manual are Direct Current (DC) unless stated otherwise.
