The Model 300T2G8 is a self contained, forced air-cooled, broadband traveling wave tube (TWT) microwave
amplifier designed for applications where instantaneous bandwidth and high gain are required. A reliable TWT
provides a conservative 300 watts minimum at the amplifier output connector. Stated power specifications are
at the fundamental frequency.
The amplifier's front panel digital display shows forward and reflected output plus extensive system status
information accessed through a series of menus via soft keys. Status indicators include power on, warm-up,
standby, operate, faults, excess reflected power warning and remote. Standard features include a built-in IEEE-
488 (GPIB) interface, 0 dBm input, VSWR protection, gain control, external video pulsing, RF output sample
port, auto sleep, plus monitoring of TWT helix current, cathode voltage, collector voltage, heater current,
heater voltage, baseplate temperature and cabinet temperature.
Modular design of the power supply and RF components allow for easy access and repair. Use of a switching
mode power supply results in significant weight reduction. The external video pulsing feature reduces prime
power use for pulse applications.
Housed in a stylish contemporary cabinet this unit is designed for benchtop use but can be removed from the
cabinet for rack mounting. The Model 300T2G8 provides readily available RF power for a variety of
applications in Test and Measurement, (including EMC RF susceptibility testing), Industrial and University
Research and Development, and Service applications.
