Instruments for Industry, T-1000 Series TWT Amplifiers provide outstanding RF performance. Their “T-1000 Series” TWTA (traveling wave tube amplifier) 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 1 GHz – 18 GHz at 1000 watts.

Operation safety and ease of use are paramount in IFI TWTA product designs. The IFI T-1000 Series amplifiers 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-1000 series TWTA products includes a state-of-the-art interface that is sophisticated, comprehensive, but yet simple to use. Their 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-1000 Series TWT (Traveling Wave Tube) amplifiers can be easily customized with harmonic filters or other options. With this capability and its reliable elegant design, the T-1000 series amplifiers are the perfect amplifier for your microwave needs. IFI amplifiers are perfect for EMI, EMC testing applications as well as instrumentation applications. IFI offers different size packages and configurations to best suit your requirements.
