本文描述一种新型的滤波式慢波结构——它可当作由电感并联加载的交插指型线。文中提出了结构的相速和阻抗的冷测研究结果。对于所研究的结构,在多条电子流与+1次空间谐波的轴向电场之间发生相互作用。此结构作为行波放大器的线路,相速和作用阻抗有宽频带性质。对于30%的频宽,相速最大偏离值为±0.3%左右。这种结构适用于毫米波段频宽为20%的高功率放大器。 This article describes a new type of filtered slow-wave structure - it acts as an interposer finger loaded in parallel by an inductor. In this paper, the results of cold measurement of phase velocity and impedance are proposed. For the structure studied, an interaction occurs between the axial electric fields of multiple electron currents and the + 1-space harmonic. This structure as a traveling wave amplifier circuit, phase velocity and the role of impedance broadband properties. For a 30% bandwidth, the maximum phase-shift deviation is about ± 0.3%. This structure is suitable for high-power amplifiers with a bandwidth of 20% in the millimeter wave band.
