Amplifier Research 750W1000 Amplifier : The Amplifier Research 750W1000 is a self-contained, aircooled, 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 Amplifier Research 750W1000, when used with an RF sweep generator, will provide a minimum of 750 watts of RF power.The Amplifier Research 750W1000 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 amplifier status. Special features include a gain control, internal automatic level control (ALC) with front panel control of the ALC threshold, forward and reflective RF sample ports for precise power measurements and RF output level protection. Protection is provided by DC cur level sensing of all output stages.All amplifier control functions and status indications are available remotely in GPIB/IEEE- 488 format and RS-232 hardware and fiber optic, USB and Ethernet. The buss 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 a single equipment rack, the 750W1000 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. A safety interlock can be implemented via a rear panel connector. Functions and Specifications of the Amplifier Research 750W1000 Amplifier Include:  RATED OUTPUT POWER: 750 watts minimum INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum POWER OUTPUT @ 3 dB compression: Nominal 900 watts, 775 watts min up to 500 MHz,725 watts from 500 to 1000 MHz POWER OUTPUT @ 1 dB compression: Nominal 750 watts, 700 watts min up to 500 MHz;600 watts min from 500 to 1000 MHz FLATNESS: ±1.5 dB maximum; ±1.0 dB typical FREQUENCY RESPONSE: 80–1000 MHz instantaneously GAIN (at maximum setting): 58.8 dB minimum GAIN ADJUSTMENT (continuous range): 25 dB minimum INPUT IMPEDANCE: 50 ohms, VSWR 1.5:1 maximum;1.3:1 typical OUTPUT IMPEDANCE: 50 ohms nominal MISMATCH TOLERANCE: 100% of rated power with- out foldback.Will operate without damage or oscillation with any magnitudeand phase of source and load impedance.  MODULATION CAPABILITY: Faithfully reproduces AM, FM, orPulse modulation appearing on input signal. HARMONIC DISTORTION: Minus 20 dBc maximum at 600 watts,-20 dBc typical @ 750 watts THIRD ORDER INTERCEPT POINT: 64 dBm typical NOISE FIGURE: 8 dB maximum, 6 dB typical PRIMARY POWER (specify voltage): 200-240 VAC, 50/60 Hz,single phase, 3200 watts
