The Amplifier Research Model 250AP250A 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 RF 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 250AP250A, when used with an RF sweep generator, will provide a minimum of 250 watts of swept power. The Model 250AP250A is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier.
