一、引言介质支撑曲折线是最近在研制正交场放大管的过程中发展起来的一种大功率、宽频带慢波结构。由于它的成就,使注入式正交场放大管在C波段和S波段的倍频程带宽内能获得一千瓦的连续波输出功率和十千瓦的峰值输出功率。采用介质支撑曲折线,还可以使体积小、重量轻著称的正交场放大管的体积和重量进一步大为减小。例如,一支采用介质支撑曲折线作为慢波结构的S波段注入式正交场放大管可成功地包装在24×12×11立方厘米的体积内,其包括磁钢在内的整管总重量仅为4.3公斤。
I. INTRODUCTION The dielectric support zigzag line is a kind of high-power, wide-band and slow-wave structure developed recently in the process of developing quadrature field amplifier. Because of its achievements, the injection quadrature field-amplifier tube can obtain one kilowatt of continuous wave output power and ten kilowatts of peak output power in the octave bandwidth of C-band and S-band. The use of media support zigzag line, you can also make small, light weight of the orthogonal field amplifier tube size and weight is further greatly reduced. For example, an S-band Injected Orthogonal Field Amplifier with a dielectric support serpentine as a slow-wave structure can be successfully packaged in a volume of 24 x 12 x 11 cm3, including the total weight of the entire tube Only 4.3 kilos.
