Le tube à ondes progressives (TOP, en anglais traveling - wave tube, TWT) est un tube à vide . des supports en oxyde de béryllium peut néanmoins atteindre et même dépasser une puissance de 1 kW CW (Continuous Wave) en bande X.
2-21 wide range of rf frequencies if it is terminated in the characteristic impedance of the line. The electromagnetic waves traveling down the line produce.
This paper describes the development of the traveling - wave tube for this .. It was found that the efficiency continued to improve as this section was...

Traveling wave tube continued flying cheap

Wherever possible attempts have been made to give explanations of the modes of operation of the various devices in simple physical terms. The result is that the beam current, which was unmodulated as it entered the helix, now has an RF component at the signal frequency. Borrowing a page from the semiconductor industry, engineers at Northrop Grumman and Teledyne Scientific Co. Pour obtenir une bonne interaction entre le faisceau et l'onde hyperfréquence qui se déplace le long de l'hélice, il faut qu'ils aient une vitesse axiale proche.

With the tube running at its specified collector current, RF drive can be applied. The frequency at which the device operates controls. The geometery of the helix. Heated, the barium continuously diffuses to the surface, forming a thin oxide layer. Recently, our colleagues at SRI have developed a feature to mitigate the damaging effects of such shorts.
