The 2126 High Power COTS Amplifier from Empower RF developed for harsh environments. The amplifier system provides up to 1 KW of power from 20 MHz to 500 MHz and is suitable for multi-octave bandwidth high power CW, modulated, and pulsed applications. This amplifier utilizes high power LDMOS transistor devices that provide wide frequency response, high gain, high peak power capability, and low distortions. It is constructed within one single 5RU drawer including the forced air-cooling. The system comes standard to operate from 180-260VAC single phase or optionally can be ordered with a three phase AC supply. This COTS amplifier has been tested for MIL-STD-810E Method 514.4 vibration 40g Peak while operational for 270 minutes in each axis. The amplifier system was mounted in the test fixture undergoing 40g shock testing while operating uninterrupted at full rated output power. The unit also passed Shock - MIL-STD 810F Method 516.5 3 Axes, Quantity 18 pulses per direction 11 mSec Sawtooth Pulse / 40g Peak.
