Instruments for Industry, T2618 Series Amplifiers provide outstanding RF performance. Our “T2618 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 power levels from 10 watts to 200
watts in the 18.0GHz-26.5GHz frequency range.
Operation safety and ease of use are paramount in IFI product designs. The IFI T2618 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 T2618 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 T2618 Series
amplifiers can be easily customized with harmonic filters or other options. With this capability and its reliable elegant design, the T2618 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!
