RF Amplifier 0.8 – 4.2 GHz 350W

Amplifier Research 350S1G4 The Amplifier Research 350S1G4 is a portable, self-contained, air-cooled, broadband, and completely solid-state ampifier designed for applications that require instantaneous bandwidth, high gain, and linearity.  Housed in a single equipment rack the Amplifier Research 350S1G4 amplifier is designed to provide complete standalone performance for RF testing or it can be used as a sub-amplifier as well.Features and Specifications of the Amplifier Research 350S1G4 Amplifier include:

• Provides a minimum of 350 watts of RF power when used with a sweep generator
• Provides gain control and RF output level protection
• Digital Control Panel (DCP):
• Provides both local and remote control of the amplifier
• Uses a graphic liquid crystal display:
• Provides operational presentation of Forward Power and Reflected Power
• Provides control status
• Provides reports of internal amplifier status
• Uses menu assigned softkeys
• Uses a single rotary knob
• Uses four dedicated switches: POWER, STANDBY, OPERATE, and FAULT/RESET
• Offers extensive control and status reporting capability
• 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 on the back panel
• Local/Remote switch on front panel provides 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.
