Amplifier Research 200S1G6 Overview

The Amplifier Research 200S1G6 is a solid state, Class A design, self-contained, air-cooled, broadband amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Housed in a stylish contemporary cabinet, the unit is designed for benchtop use, but can be removed from the cabinet for immediate equipment rack mounting.

Features:

• When used with a sweep generator, provides a minimum of 200 watts of RF power
• Front panel gain control allows convenience of setting desired output level
• Protected from RF input overdrive by an RF input leveling circuit which controls the RF input level to the RF amplifier first stage when the RF input level is increased above 0 dBm
• Stages are protected from over-temperature by removing the DC voltage to them if an over-temperature condition occurs due to cooling blockage or fan failure
• Digital display on front panel indicates operate status and fault conditions if an over-temperature or power supply fault has occurred
• Unit can be returned to operate when the condition has been cleared 
• All control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB and Ethernet
• Bus interface connector is located on back panel
• Local/Remote switch on front panel assures postive control of local or remote operation
• Applications:
• Low level of spurious signals and linearity make amplifier ideal for use as a driver amplifier in testing wireless and communication components and subsystems
• Can be used as a test instrument covering multiple frequency bands
• Suitable for a variety of communication technologies including CDMA, W-CDMA, TDMA and GSM
• Suitable for EMC Test application where undistorted modulation envelopes are desired
