Amplifier Research 100W1000M11

The Amplifier Research 100W1000M11 is a solid-state RF amplifier delivering 100 W of broadband power across 1 MHz to 1 GHz. Engineered for EMC testing, wireless communications, and laboratory applications, this air-cooled unit combines high gain with low distortion and linear signal amplification. Push-pull circuitry in the high-power stages minimizes harmonic content and ensures stability across the full frequency range.
