Amplifier Research 1W1000B

The Amplifier Research 1W1000B is a solid-state, broadband RF power amplifier engineered for RF susceptibility testing, antenna characterization, and precision measurement applications. This self-contained, air-cooled unit delivers 1 watt minimum continuous output across 100 kHz to 1000 MHz with 30 dB gain and exceptional load-tolerance performance. The amplifier maintains ±1.0 dB flatness across its operating bandwidth and faithfully reproduces AM, FM, and pulse modulation without distortion.

It accepts input levels as low as 1.0 mW for rated output and operates without damage under any load impedance condition - including 100% mismatch - while limiting reflected power to 100 watts.
