Amplifier Research 500A250C Amplifier (Call for availabilty)The Amplifier Research 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 Amplifier Research 500A250C, when used with an RF sweep generator, will provide a minimum of 500 watts of swept power. The Amplifier Research 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. Housed in a stylish, contemporary enclosure, the Amplifier Research 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.Functions and Specifications of the Amplifier Research 500A250C Amplifier Include:RATED OUTPUT POWER: 500 watts INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum POWER OUTPUT @ 3 dB compression Nominal: 600 wattsMinimum: 500 watts POWER OUTPUT @ 1 dB compression Nominal: 500 wattsMinimum: 350 watts FLATNESS: 2.5 dB maximum FREQUENCY RESPONSE: 10 kHz–250 MHz instantaneously GAIN (at maximum setting): 57 dB minimum GAIN ADJUSTMENT (continuous range): 20 dB minimum INPUT IMPEDANCE: 50 ohms, VSWR 1.5:1 maximum OUTPUT IMPEDANCE: 50 ohms, nominal MISMATCH TOLERANCE: 100% rated power without foldbackup to 6.0:1 mismatch, above which may limit to 250Wreflected power.
