The AA-12G-4KW-PT from Advanced Amplifiers is a TWT Power Amplifier that operates from 1 to 2 GHz. It delivers a peak pulsed output power of 4 kW with a gain of 40 dB and a duty cycle of 6%. This amplifier has spurious emissions of better than -55 dBc for frequencies up to 250 Hz and -60 dBc for frequencies above 250 Hz. It combines modern TWT (Travelling Wave Tube) technology with advanced internal monitoring capabilities for reliable operation. This amplifier is available in a 5U chassis that measures 28.00 x 19.00 x 8.75 inches with Ethernet and RS-232 digital interfaces. It has built-in protection circuits and is ideal for linear high-peak pulse applications.
