T-500 Series High Power TWT Microwave Power Amplifiers
1.0 – 18 GHz • 500 watts, Minimum Rated Power
Instruments for Industry, T-500 Series Amplifiers provide outstanding RF performance. Our “T-500 Series”
products are a mature design but incorporate the latest features with respect to control and monitoring. These
amplifiers are “State of the Art”; have field proven reliability and unsurpassed performance as the best in the
industry. These products are available in a wide range of frequency bands from 1GHz-18GHz at 500 watts.
Operation safety and ease of use are paramount in
IFI
product designs. The IFI T-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. In addition, the T-500
series includes a state-of-the-art interface that is sophisticated, comprehensive, but yet simple to use. Our
amplifiers feature 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.
The backlit LCD screen shows forward/reverse power indication, system status and self-diagnostic information.
All the amplifier operating parameters are simultaneously available in the amplifier front panel display as well as
over the remote bus. Selection switches allow you to switch the amplifier to the desired mode of operation for
local control if the unit is not being operated remotely.
For computer automation both an RS-232 and IEEE-488 interface are included. To meet individual application
needs, the
T-500 Series amplifiers can be easily customized with harmonic filters or other options. With this capability and
its reliable elegant design, the T-500 series amplifiers are the perfect amplifier for your microwave needs.
IFI
offers different size packages and configurations to best suit your application. A product and design built to last!
