Amplifier Research 600A225A Amplifier :The Amplifier Research 600A225A 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 600A225, when used with an RF sweep generator, will provide a minimum of 600 watts of swept power. The Amplifier Research 600A225 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a 3.75 inch diagonal graphic display, menu assigned softkeys, a single rotary knob, and four dedicated switches 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, 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 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 keylock 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 600A225 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 Amplifier Research 600A225A Include: RATED OUTPUT POWER: 600 watts INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum POWER OUTPUT @ 3 dB compressionNominal: 600 wattsMinimum: 550 watts POWER OUTPUT @ 1 dB compression Nominal: 550 wattsMinimum: 400 watts FLATNESS: 2.5 dB maximum FREQUENCY RESPONSE: 10 kHz–250 MHz instantaneously GAIN (at maximum setting): 58 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 300W reflected power.Will operate without damage or oscillation with any magnitude andphase of source and load impedance. MODULATION CAPABILITY: Will faithfully reproduce AM, FM,or pulse modulation appearing on the input signal HARMONIC DISTORTION: Minus 20 dBc maximum at 400 watts THIRD ORDER INTERCEPT POINT: 65 dBm typical RF POWER DISPLAY: 0–750 watts full scale PRIMARY POWER: 180–264 VAC 47–63 Hz, 2500 wattsmaximum @ 0.99 P.F. typical
