Amplifier Research 3000W1000A RF Amplifier 80 MHz – 1000 MHz 3000W
Description
Amplifier Research 3000W1000A is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability.
The Model 3000W1000A, when used with a sweep generator, will nominally provide over 3000 watts of RF power.
The Model 3000W1000A is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a 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/external automatic level control (ALC) with front panel control of the ALC threshold, pulse input capability and RF output level protection. Also included is an internal RF detector which provides an output for use in self-testing or operational modes.
All amplifier control functions and status indications are available remotely in GPIB / IEEE-488.2 format, and RS-232 fiber optic. The bus interface connector is 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.
Housed in stylish, contemporary equipment racks, the Model 3000W1000A provides readily available RF power for typical applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, and as a driver for frequency multipliers and higher power amplifiers.
The 3000W1000A consists of three 1000 watt amplifiers which can be operated as independent individual amplifiers and a controller/driver equipment rack.
