75A250 Amplifier Research RF Amplifier

Used
The 75A250 is a 250 MHz 75 Watt RF Amplifier from Amplifier Research. Amplify RF and Microwave signals to measure, test, and design circuits. Applications include radio communications, cellphones, EMI testing, and much more.

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.
