Product description
The Amplifier Research 25A250 is an RF amplifier which features a frequency range of 10kHz to 250MHz and 25W minimum output power. The AR 25A250 is a self-contained, broadband 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. The AR 25A250, when used with an RF sweep generator, will provide a minimum of 25 watts of swept power. The AR 25A250 includes a front panel control which permits the operator to conveniently set the amplifier's desired output level. This unit will also faithfully reproduce AM, FM, or pulse modulation appearing on the input signal.
