The PT series of KW Pulse amplifiers built by IFI; are high power, “State-of-the-art” Pulse TWT amplifiers specifically
designed for microwave testing applications. Our elegant approach provides 2000-4000 Watts of pulse power for various
frequency ranges from 1.0 to18.0 Gigahertz in various packages that offers all the controls and communications needed for
today's automated test systems. These amplifiers have field proven reliability and unsurpassed performance as the best in the
industry.
From the ground up the PT series amps are built to withstand rugged handling, whether it's being shipped to you or hauled
around from site to site. 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.
Redundant thermal and airflow sensors prevent the TWT from overheating. In addition, high VSWR protection is built in.
The PT series “State-of-the-art” interface is sophisticated yet simple to use. The backlit LCD screen shows forward/reverse
power indication, 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-488 interface are included. To meet individual requirements, the PT series amplifiers can be easily customized
with our available options that may be required for your application.
With all this capability and its reliable elegant design, the PT series amplifiers are the perfect amplifier for your testing needs.
