The Model 75A220 is a self-contained, broadband amplifier for laboratory applications requiring instantaneous bandwidth, high gain, and moderate power output. This amplifier is packaged in a small, stylish laboratory type cabinet and is ideal for applications such as RF susceptibility testing, antenna and component testing, wattmeter calibration and as a driver for higher amplifiers. The unit also features a front panel gain control which permits the operator to conveniently set the desired power output level.
