The Model 1500T8G18 is a self-contained, forced air-cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth, high gain, moderate harmonic levels, and high power output are required. Reliable TWT subsystems provide a conservative 1500 W 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, 0dBm input, VSWR protection, gain control, RF output sample ports, auto sleep, plus monitoring of TWT helix current, cathode voltage, collector voltage, heater current, heater voltage, baseplate temperature, and cabinet temperature. The modular design of the power supply and RF components allows for easy access and repair. Use of a switching mode power supply results in significant weight reduction.
The rated power is developed by efficient power combining the outputs from four 500 W (nominal) microwave amplifiers, each consisting of two TWTs, that are factory matched in gain and phase, resulting in an excellent combination of wide instantaneous bandwidth with improved harmonic levels. Shipped as two cabinets, this model includes castor wheels and lifting eyes on each cabinet to facilitate positioning the amplifier, and leveling feet to stabilize the unit during operation.
The Model 1500T8G18 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.
