500T8G18
The Model 500T8G18 is a self-contained, forced air-cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth, reduced harmonics, and high gain are required. A reliable TWT subsystem provides a conservative 500 W minimum at the amplifier output connector. Stated power specifications are at the fundamental frequency.
Overview
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, 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.
