The Model 1500T2G8A is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth, high gain, moderate harmonic levels, and high power output are required. Reliable TWT subsystems provide a conservative 1600 watts minimum at the amplifier output connector. Stated power specifications are at fundamental frequency.
