Amplifier Research 75AP250 Overview

The Model 75AP250 is a self-contained, air cooled, broadband, solid state amplifier designed for applications where pulsed, high power, RF outputs are required. For NMR applications, the amplifier incorporates high speed blanking and gating circuitry, which generally reduces output noise and increases R.F. on/off attenuation. This feature is especially suited for NMR applications as well as more general applications. Push-pull MOSFET circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 75AP250, when used with an RF sweep generator, will provide a minimum of 75 watts of swept power. Also included is a front panel gain control which permits the operator to conveniently set the desired power output level. High efficiency, universal input, switching power supplies provide reliable DC to all internal sub-assemblies.
