IFI GT825-500 High Power Pulse TWT Amplifier 2.5 - 8 GHz, 500 Watt

The IFI GT-500 Series include a full complement of RF and hardware protection systems including high VSWR, over-current and voltage protection as well as redundant thermal and airflow sensors to prevent the TWT from overheating.

It features modular construction and this concept of modular design minimizes internally produced EMI signal leakage and provides easy access for field service and rapid turnaround at depot level repair facilities.
