The Model 100T40G50 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 subsystem provides a conservative 100 W minimum, measured at the amplifier output flange. 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 ports, 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 two microwave tubes that are factory-matched in gain and phase.
