最常见的微波真空管，如速调管，使用密度调制电子束在设备的输出部分激发电磁场。在本文中，我们提出了一个概念，称为轨迹或偏转调制的光束具有均匀的纵向速度调制通过改变其横向位置。这允许电子的相当均匀的减速，这提高了效率，并在毫米波管的设计中带来了新的可能性。在这篇文章中，我们将讨论基于不同类型调制器的圆偏转调制器件的优点，并将展示它们如何用于倍频。
Most common microwave vacuum tubes like klystrons use a density modulated electron beam to excite electromagnetic fields in the output section of the device. In this paper we present a concept called trajectory or deflection modulation where a beam with an uniform longitudinal velocity is modulated by changing its transverse position. This allows a quite uniform deceleration of the electrons what enhances the efficiency and leads to new possibilities in the design of millimeter wave tubes. In this manuscript we will discuss the advantages of circular deflection modulated devices based on different types of modulators and it will be shown how they can be used for frequency multiplication.
