40T18G26A
The Model 40T18G26A is a self-contained, forced air-cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where wide instantaneous bandwidth, high gain, and moderate power output are required. A reliable TWT provides a conservative 40 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, 0dBm 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. 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.
