The Amplifier Research 40S1G4 is a solid state, self-contained, air-cooled, broadband amplifier designed for applications where instantaneous bandwidth, high gain, and linearity are necessary. It is housed in a stylish cabinet, designed for benchtop use, but can also be removed for immediate equipment rack mounting.
Features and Specifications of the Amplifier Research 40S1G4 include:
Features:
Provides a minimum of 40 watts of RF power when used with a sweep generator
Front panel gain allows convenience of setting desired output level
RF input leveling circuit:
Controls the RF input level to the RF amplifier first stage when the RF input level is increased above 0 dBm
Protects the amplifier from RF input overdrive
RF amplifier 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 the front panel indicates the operate status and fault conditions when an over-temperature or power supply fault has occurred
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 the back panel
Local/Remote switch on front panel assures positive control of local or remote operation
Low level of spurious signals and linearity make it ideal for these various uses:
As a driver amplifier in testing wireless and communication components and subsystems
As a test instrument covering multiple frequency bands
For communication technologies including CDMA, W-CDMA, TDMA, GSM, etc.
For EMC Test applications where undistorted modulation envelopes are needed
