Abstract
A delay line for traveling-wave tubes, particularly a wideband low-reflection attenuated line for millimeter waves, in the form of a hollow guide having successive transverse walls which define successive line cells, each of such walls having a central opening for the passage of the electron beam and at least one coupling opening, elongated attentuating members being disposed in the respective cells with their longitudinal axes extending parallel to the longitudinal axis of the delay line. The attenuating members are of like effective length and the matching cell lying immediately ahead of and/or behind the attenuating section of the tube contains, in each case, at least one matching member.
Claims12
In a wide-band, low-reflection attenuated delay line for traveling wave tubes, particularly for the amplification of millimeter waves, the combination of a hollow guide forming an attenuation section having transverse walls defining respective line cells therebetween, which walls each having a central opening for the passage of the electron beam and at least one coupling slot, elongated attenuating members disposed in the respective cells with their longitudinal axes extending at least approximately parallel to the longitudinal axis of the delay line, said attenuating members having a substantially uniform effective penetration depth within the associated cells, and a line cell, forming a matching cell, disposed directly ahead of and/or behind the attenuation section for matching the latter to an adjacent section of the delay line, said matching cell, in each case, containing at least one matching member therein.
