Amplifier Research 75A250A RF Amplifier 10 kHz to 250 MHz, 75 Watts

The Amplifier Research 75A250A amplifier is a portable, self-contained, air-cooled, broadband, solid state amplifier 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. When used with an RF sweep generator, the 75A250A will provide a minimum of 75 watts of swept RF output power.

The Model 75A250A includes a front panel RF Gain Control, which permits the operator to conveniently set the amplifier's desired output level.
