IFI T251-500A TWT Amplifier | 0.8 GHz – 2.5 GHz, 500 W

The IFI T251-500A TWT Amplifier has a frequency response of 0.8 GHz – 2.5 GHz (functional), 500 W minimum (250 – 500 W nominal) designed for precompliance testing in accordance with FCC Part 15. It contains three supplies of Helix, Collector, and Filament, wherein the Helix supply provides negative high voltage potential between the cathode and ground. Meanwhile, the Collector supply is a high voltage supply between the cathode and itself, and the Filament supply provides heater voltage and floats at high voltage cathode potential.
