The 2221 from Empower RF Systems is a solid-state broadband high-power amplifier that operates from 9 to 10 GHz and produces a minimum output of 8kW peak pulsed power. It has a pulse width of 0.2 - 500 μSec and a duty cycle of 0.5 - 20%. This amplifier has a power gain of 70 dB, a pulse droop of 2 dB and a modulated pulse rise/fall time of 25 nsec. It has an input return loss of -10 dB and a power gain flatness of +/- 1 dB. It includes a built-in control and monitoring system, with protection functions that preserve maximum output capability and reliability. This system has a harmonic of -40 dB and a spurious of -60 dB. 

The 2221 features multiple high-power GaN on SiC devices that provide wide frequency response, high gain, high peak power capability, and low distortions. It consists of an extended memory, internal forced air-cooling fans and interfaces. The system comes standard to operate from a 180-260VAC 3-phase power source.
