AR’s 12500A2225A-L liquid-cooled, RF solid state CW amplifier is the new industry standard for radiated immunity testing of entire automobiles, producing 12,500 watts over the instantaneous 10 kHz to 225 MHZ frequency band with harmonic distortion less than -20 dBc.

Central to its design is the flexible liquid-cooling system which improves thermal management and extends the life of critical amplifier components. Special features include the option for user or AR supplied chiller, gain control, internal automatic level control (ALC) and RF output level protection. For more information visit
