The Amplifier Research Model 1000TP1G3 is a self contained, forced air cooled, dual band traveling wave tube (TWT) microwave amplifier designed for pulse applications at low to moderate duty factors where dual band operation and high gain are required. A reliable TWT provides a conservative 1000/475 watts minimum peak RF pulse power at the amplifier output connector. Stated power specifications are at the fundamental frequency. The amplifier's front panel digital display shows forward and reflected average power output or forward and reflected peak power, plus extensive system status information accessed through a series of menus via soft keys.
