Product Overview

Rent Amplifier Research 1000A225 Amplifier (call for availability)

The Amplifier Research 1000A225 is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required.

Push-pull MOSFET circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Amplifier Research 1000A225 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a 3-¾ inch diagonal graphic display, menu assigned softkeys, a single rotary knob, and four dedicated switches (POWER, STANDBY, OPERATE and FAULT/RESET) to offer extensive control and status reporting capability. The display provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status.

Special features include a gain control, internal automatic level control (ALC) with front panel control of the ALC threshold and RF output level protection. RF Sample Ports are included to monitor forward and reverse power. All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format, and RS-232 hard wire and fiber optic and USB. The bus interface connectors are located on the back panel and positive control of local or remote operation is assured by a keylock on the front panel of the amplifier. High-efficiency, universal-input, power-factor-corrected switching power supplies provide DC to all internal subassemblies.

Housed in a stylish, contemporary enclosure, the Amplifier Research 1000A225 provides readily available RF power for typical applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, particle accelerators, plasma generation, communications and use as a driver for higher power amplifiers.
