IFI S21-Series Solid State Microwave Power Amplifier
Instruments for Industry, S21 Series Solid State amplifiers are state-of-the-art amplifiers and provide outstanding RF performance. The S21 Series amplifiers operate over the frequency range from 0.8 – 2.0 GHz and can be supplied at power levels from 10 watts to 2000 watts offering all the control and communication features needed for today’s automated test systems. From the ground up, the S21 Series amplifiers are built to withstand rugged handling, whether it’s being shipped to you or hauled around from site to site. They feature heavy-duty aluminum chassis construction with a modular approach for easy access and service.
Operation safety and ease of use are paramount in IFI product designs. The IFI S21 Series include a full complement of RF and hardware protection circuits including high VSWR, over-current, voltage protection, redundant thermal and airflow sensors for the module and the system level. In addition, the S21 series includes a state-of-the-art interface that is sophisticated, comprehensive, and yet simple to use.
The backlit LCD screen shows forward/reverse power indication, system status and self-diagnostic information. All the amplifiers 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 interface are provided as standard. To meet individual application needs, the S21 Series amplifiers can be easily customized with other options. With this capability and its reliable elegant design, the S21 series amplifiers are the perfect system for your applications.
