Amplifier Research 75A250A for Rent, RF Amplifier, 10kHz - 250MHz, 75W

Product Highlights

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. 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. The digital display on the front panel indicates the operation status and any pending fault conditions when an over temperature or power supply fault has occurred.

Housed in a stylish contemporary enclosure, the unit provides instantaneous power for typical applications such as RF susceptibility testing, antenna and component testing, Watt-meter calibration and as a driver for higher power amplifiers. The 75A250A is powered by a high efficiency switching supply, with autoranging AC input circuitry which will automatically accept voltages from 90 to 135 VAC, or from 180 to 270 VAC, in the 47 to 63 Hz frequency range. The 8-bit RISC microprocessor controller board provides IEEE-488 (GPIB) and asynchronous full duplex RS-232 communication control of all amplifier functions.
