Amplifier Research 300TR2z5G7z5 TWT Amplifier 2.5 GHz – 7.5 GHz 300W
Description
Amplifier Research 300TR2z5G7z5 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, 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.
This unit is designed for 19 inch rack mounting, offers four side mounted carry handles, plus non-slip feet for bench top use.
Model 300TR2z5G7z5 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.
