The Amplifier Research Model 4W1000 Amplifier is a self-contained broadband unit designed for laboratory applications where instantaneous bandwidth, high gain and moderate power output are required. Solid state technology is used exclusively to offer significant advantages in reliability and cost. A model 4W1000 used with a frequency swept signal source will provide 4 watts of linear output power from 1-900 MHz, or 3.5 watts from 1-1000 MHz. Typical applications include antenna and component testing, use as a driver for frequency multipliers and high power amplifiers and as an RF source for nuclear magnetic resonance studies.
