Amplifier Research 10W1000

The Amplifier Research 10W1000 is a solid-state, air-cooled broadband RF power amplifier delivering 10 W continuous output across 1 MHz to 1000 MHz. This self-contained instrument combines Class A push-pull circuitry with 40 dB minimum gain, ±1.0 dB typical flatness, and unconditional stability across any load impedance. It accepts maximum 1.0 mW input and provides 20 dB continuous gain adjustment.
