Description

Traveling Wave Tubes or TWTs are specialized vacuum tubes that are used in electronic systems to amplify radio frequency (RF) signals in the microwave range. Many TWTs operate by absorbing the power from a beam of electrons as they pass down the tube. Photonis Defense’s TWTs are of the helix variety in which a wire helix surrounds the beam causing radio waves to interact with the electron beam. Widely used as the power amplifiers and oscillators in radar systems, communication satellites, airborne military platforms and electronic warfare systems, Photonis’ Continuous Wave or CW Traveling Wave Tubes offer superior wide-band performance. The tubes are of ceramic-metal construction, the industry standard, for durability in some of the most severe environmental conditions. By using rare-earth periodic permanent magnets, Photonis TWTs do not require additional power for accurate focusing. For applications where a High Voltage Power Supply might be required, Photonis’ CW Traveling Wave Tubes can be supplied with a military grade HVPS. This allows users to operate the traveling wave tube from various military power sources. The technical information chart above only shows a brief selection of Photonis’ fully customizable CW Traveling Wave Tube designs, should you have a specific CW Traveling Wave Tube requirement Photonis Defense can work with you to create a custom solution.
