Product Overview

RENT Amplifier Research 175S1G4 (Call for Availability)

The Amplifier Research 175S1G4 is a portable, self-contained, air-cooled, broadband, and completely solid-state ampifier designed for applications that require instantaneous bandwidth, high gain, and linearity. Its push-pull circuitry is utilized in all power stages lowering distortion and improving stability.

Features and Specifications of the Amplifier Research 175S1G4 Amplifier include:

  • Features:
    • Provides a minimum of 175 watts of RF power when used with a sweep generator
    • Digital Control Panel (DCP):
      • Provides both local and remote control of the amplifier
      • Uses a digital 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
    • Gain control and RF output level protection
    • 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 back panel
    • Keylock 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:
      • A driver amplifier in testing wireless and communication components and subsystems
      • A test instrument covering multiple frequency bands
      • For communication technologies including CDMA, W-CDMA, TDMA, GSM, etc.
