Photonis’ tubes are used for electronic countermeasures, radar applications, airborne military platforms, rack mount amplifiers, communications and SatCom systems.
DESCRIPTION
Since their invention in the early 1940’s Photonis and its predecessors have been designing and manufacturing helix-type Traveling Wave Tubes for numerous defense applications. These helix-type traveling wave tubes are constructed using the industry standard of metal-ceramic and feature rare-earth periodic permanent magnets for power-free focusing. Many of Photonis’ tubes are used for electronic countermeasures, radar applications, airborne military platforms, rack mount amplifiers, communications and SatCom systems. For these applications, Photonis has designed their various Traveling Wave Tubes to be conduction cooled for reliable operation in high altitude and temperature environments. Photonis offers a variety of CW, Pulsed, Narrow and Wide Band TWTs that can be customized to meet specific application requirements. Explore our Traveling Wave Tube offerings below. If you would like to discuss creating a custom tube for your requirement or have questions please contact us to speak with a TWT specialist.
