Amplifier Research 500A250C

 AR-500A250C 500Watt, CW 10kHz-225MHz RF Power Amplifier

The  AR-500A250C is a self-contained, air-cooled, broadband, completely solid
state amplifier designed for applications where instantaneous bandwidth and
high gain are required. Push-pull LDMOS circuitry is utilized in all high
power stages in the interest of lowering distortion and improving stability.
The  AR-500A250C, when used with an RF sweep generator, will provide a minimum
of 500 watts of swept power.

The  AR-500A250C is equipped with a Digital Control Panel (DCP) which provides
both local and remote control of the amplifier. The DCP uses a color LCD touch
screen and a single rotary knob to offer status reporting and control
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, pulse input capability, forward RF
sample port, and a reflective RF sample port for precise power measurements.

All amplifier control functions and status indications are available remotely
in GPIB/IEEE-488, RS-232, RS-232 fiber optic, Ethernet and USB format. The
buss interface connectors are located on the back panel and positive control
of local or remote operation is assured by a switch on the front panel of the
amplifier. High efficiency universal input, power factor corrected switching
power supplies provides DC to all internal subassemblies.

The  AR-500A250C 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.

The export classification of this equipment is EAR99.
