The Amplifier Research 50A220 is a self-contained, air-cooled solid-state RF power amplifier engineered for broadband applications across EMC testing, laboratory work, and communication systems. It delivers a minimum of 50 watts across 10 kHz to 220 MHz with push-pull MOSFET circuitry optimized for stability and low distortion. The amplifier operates reliably into any load impedance without damage, foldback, or shutdown—handling 100% rated power across all magnitude and phase conditions.
