75A250 Amplifier Research RF Amplifier
The Amplifier Research 75A250 amplifier is a self-contained, broadband unit designed for laboratoryapplications where instantaneous bandwidth, high gain and moderate power output are required.Utilization of push-pull MOSFET circuitry lowers distortion, improves stability and allowsoperation into any load impedance without damage. The Model 75A250, when used with an RFsweep generator, will provide a minimum of 75 watts of swept power.
The Model 75A250 includes a front panel control which permits the operator to conveniently setthe amplifier's desired output level. Housed in a stylish contemporary enclosure, the Model75A250 provides readily available RF power for typical applications such as RF susceptibilitytesting, antenna and component testing, watt meter calibration, and use as a driver for higherpower amplifiers.The 75A250 utilizes a switching power supply with a universal, autoranging input which willautomatically accept from 90 to 135 VAC or from 180 to 270 VAC at 47 to 63 Hz.
