The Model 40AD1 amplifier is a self-contained, broadband unit designed for laboratory applications where instantaneous bandwidth, high gain and moderate power output are required. Utilization of push-pull MOSFET circuitry lowers distortion, improves stability and allows operation into any load impedance without damage. The Model 40AD1, when used with an RF sweep generator will provide a minimum of 40 watts of swept power. The Model 40AD1 is direct coupled throughout, allowing very low frequency signals to be used. Included is a front panel gain control which permits the operator to conveniently set the desired output level. Housed in a stylish, contemporary enclosure, the Model 40AD1 provides available RF power for typical applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, and use as a driver for high power amplifiers. The Model 40AD1 amplifier uses universal input line voltage switching power supplies, thus allowing its use over a wide range of input voltages without wiring or switch position changes. SPECIFICATIONS POWER OUTPUT, CW: Minimum 40 watts; Typical 50 watts; Linear @ 1dB compression 25 watts minimum FLATNESS: ?1.5 dB max. FREQUENCY RESPONSE: DC - 1MHz instantaneously INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum GAIN (at maximum setting): 45 dB minimum GAIN ADJUSTMENT (continuous range): 18 dB minimum INPUT IMPEDANCE: 50 ohms, VSWR 1.5:1 max. OUTPUT IMPEDANCE: 50 ohms, VSWR 2.0:1 max. MISMATCH TOLERANCE: 100% of rated power without foldback. Will operate without damage or oscillation with any magnitude and phase of source and load impedance. MODULATION CAPABILITY: Will faithfully reproduce AM, FM, or pulse modulation appearing on the input signal HARMONIC DISTORTION: Maximum at 25 watts output, -25 dBc THIRD ORDER INTERCEPT POINT: 54 dBm, typical PRIMARY POWER: 90 - 135 / 180 - 270 VAC 50/60Hz single phase autoranging 400 watts maximum.
