The Model 1000A225 is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. Push-pull MOSFET circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. RATED OUTPUT POWER: 1000 watts INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum POWER OUTPUT @ 1 dB COMPRESSION: 900 watts nominal 700 watts minimum FREQUENCY RESPONSE: 10 kHz–225 MHz instantaneously GAIN (at maximum setting): 61 dB minimum FLATNESS: ± 3.5 dB maximum ± 0.8 dB with internal leveling 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 foldback up to 6.0:1 mismatch above which may limit to 500 watts reflected power. MODULATION CAPABILITY: Will faithfully reproduce AM, FM or Pulse modulation appearing on the input signal. HARMONIC DISTORTION: Minus 20 dBc maximum at 750 watts THIRD ORDER INTERCEPT POINT: 68 dBm typical RF POWER DISPLAY: 0–2000 watts full scale PULSE MODE GATING CHARACTERISTICS Signal (into 50 ohms): + 2.0 to 6.0 VDC Rise Time: 0.5 microseconds maximum Fall Time: 0.5 microseconds RF RISE/FALL TIME: 10 nanoseconds maximum PRIMARY POWER 187–264 VAC 47–63 Hz, single phase (user must specify) 5,000 watts maximum at .95 P.F. typical CONNECTORS RF Input: See Model Configurations RF Output: See Model Configurations Forward RF Sample: Type BNC female on front panel Reverse RF Sample: Type BNC female on front panel Remote Control: 24 pin female GPIB/IEEE-488, 9-pin RS-232 and USB connectors on rear panel Remote Control (Fiber Optic): ST connector. Tx and Rx RS-232. Safety Interlock: 15 pin female Type D on rear panel IEEE-488 (GPIB) INTERFACE & RS-232: Allows control of all amplifier functions and monitoring of all status indications.
