IFI T4026 Millimeter RF TWT Amplifier Series

The IFI T4026 Millimeter RF TWT Amplifier series demonstrates excellence in RF performance, their signature Traveling Wave Tubes (TWT) allowing for an uber-wide frequency range of 26.5 – 40.0 GHz.

These innovative amplifiers have field-proven reliability and a long record of excellence in the industry. The IFI T4026 series is available in an array of power levels ranging from 10 to 200 watts/min. of rated power and from 40 to 53 dB/min. of gain. The IFI T4026’s 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. Election switches allow you to switch the amplifier to the desired mode of operation for local control if the unit is not being operated remotely.

Operation safety and ease of use are foremost in IFI’s product design process. IFI T4026 Series products 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. 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. For computer automation, both an RS-232 and IEEE-4888 interface are included. To meet individual application needs, the T4026 series amplifiers can be easily customized with harmonic filters or other options. With this capability and its reliable, elegant design, the T4026 series amplifiers are the perfect amplifier for your microwave needs, even offering different size packages and configurations to best suit your application.

The IFI T4026 Millimeter RF TWT Amplifier series includes the following models: the T4026-10, T4026-25, T4026-40, T4026-50, T4026-80, T4026-100, T4026-125, and the T4026-200. Customize your quote to select the correct model.
