e2v releases world leading broadband mini TWTs

e2v has announced the introduction of 2 new broadband mini helix Traveling Wave Tubes (TWTs).

The first tube is designed to operate at between 4.5 and 18GHz and is available now, the second, designed to operate between 2 and 18GHz will be released into production later this year. The 4.5-18GHz TWT offers world leading size, weight and performance figures, whilst the 2-18GHz TWT is unique in its broadband capability.

The broadband operation of these new tubes delivers a first for systems designers, the opportunity to replace multiple tubes within a system with a single tube, delivering savings on system size, weight, power requirements and cost.

These TWTs extend e2v’s extensive range of coupled cavity and helix TWTs designed for the exacting requirements of commercial and military applications including radar, satellite uplinks, Electronic Countermeasures (ECM) and laboratory testing equipment.

Tony Challis e2v’s Helix TWT product manager commented “We developed these tubes specifically as a result of our involvement with the global defence community”, adding “feedback from our detailed test results has already been extremely positive, with system flexibility, cost and efficiency improvements leading to some very interesting electronic countermeasure project proposals”.
