Miniature Traveling Wave Tubes

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 18 GHz
Provide high power amplification across specific frequency ranges
Ideal for portable and mobile applications where SWaP is considered

Description

Photonis was the first Vacuum Electron Device company to apply fast warm-up technology to Miniature Traveling Wave Tubes (TWTs) in a production environment. Our miniature TWTs are helix-type and feature periodic permanent magnets or PPMs for power-free focusing. These miniature TWTs are conduction cooled and are capable of supporting applications from approximately 2 to 18 GHz. Ideal for portable and mobile applications where SWaP is considered, Photonis’ miniature TWTs provide high power amplification across specific frequency ranges. These TWTs are typically used for electronic countermeasures, radar applications, airborne military platforms, rack mount amplifiers, communications, and SatCom.
