    • A traveling-wave device for amplification of RF signals at microwave frequencies, primarily from UHF to submillimeter wavelengths, comprised primarily of broad-coupled parallel striplines of which one is a cathode stripline and the other a non-intercepting gate stripline disposed between conducting plates. Electrons are emitted from the cathode stripline and accelerated by DC electric fields through the non-intercepting gate stripline on which the microwave signal is propagating in a transmission mode which has reversed directions of the microwave electric field on each side of the gate stripline. The odd mode component of the microwave electric field, between the gate stripline and cathode stripline, serves to modulate and/or stimulate electron emission from the cathode stripline and the reversed direction of the microwave electric field between the gate stripline and the conducting plate decelerates the electrons to add their energy to the propagating wave for amplification. Positive feedback, due to the coupling of the growing RF propagating wave of the stripline system to the odd mode modulating signal, gives the amplifier large and continuous exponential gain.
    • 主要由UHF至亚毫米波长的微波频率放大RF信号的行波装置主要由广泛耦合的平行带状线组成,一条是阴极带状线,另一条是设置在导电板之间的非截止栅极线。 电子从阴极带状线发射,并通过直流电场加速,通过微波信号传播的非截止栅极带状线,其在栅极线的每一侧具有相反的微波电场方向的传输模式。 栅极带状线和阴极带状线之间的微波电场的奇数分量用于调制和/或刺激来自阴极带状线的电子发射,并且栅带状线与导电板之间的微波电场的相反方向减速 电子将它们的能量加到传播波上进行放大。 由于带状线系统生长的RF传播波与奇模调制信号的耦合,正反馈给予放大器大而连续的指数增益。

    • There is disclosed a traveling wave tube with a slow wave structure having means for frequency and directionally sensitive wave amplification. The slow wave structure includes a conductive helix coaxially mounted within a conductive tubular housing and a conductive support structure longitudinally disposed within the housing and extending transversely from the helix to the housing. In some embodiments, the support structure is combshaped and in one embodiment is a helical ridge wound in registration with and in the same sense as the helix. The pitch of the housing and a preselected parameter of the support structure are simultaneously varied along the length of the helix such that a wave at a given frequency band traveling along the slow wave structure in a first direction is preferentially amplified with respect to waves traveling in an opposite direction. In various embodiments discussed, the first direction is the direction of travel of the electron beam, thereby providing a traveling wave tube which operates as a forward wave amplifier in which backward waves are suppressed.
