Photonis Defense has been manufacturing Traveling Wave Tubes (TWTs) since their invention in the early 1940s. The company began making Miniature Traveling Wave Tubes in 1972 and developed the first micro TWT in the early 1980s.
Support applications from approximately 2 to 37 GHz
Provide high power amplification across specific frequency ranges
Ideal for portable and mobile applications where SWaP is considered

Description
Photonis Defense was one of the first to introduce metal-to-ceramic construction to the industry which is now considered the standard. They where also the first to apply fast warm-up technology to Miniature Traveling Wave Tubes in a production environment. Photonis manufactures helix-type TWTs with periodic permanent magnet (PPM) focusing providing excellent broadband performance. The majority of Photonis TWTs are conduction cooled.
