The Amplifier Research (AR) 40AD1 is a self-contained, broadband, solid-state amplifier designed for laboratory applications where instantaneous bandwidth, high gain and moderate power output are required. Housed in a stylish, contemporary enclosure, the AR 40AD1 Amplifier provides available RF power for typical applications including RF susceptibility testing, antenna and component testing, watt meter calibration, and use as a driver for high power amplifiers. This amplifier uses universal input line voltage switching power supplies, allowing its use over a wide range of input voltages without wiring or switch position changes.
