Abstract

A helical (Slow Wave Structure SWS) traveling wave tube (TWT) operating in the C bandwidth was designed using CST software. Based on modelling, TWT components were produced. Conductor support rod rings were used to matching the impedance line and provide ease of assembly. According to the modelling, the signal gain was determined as 30 dB. In addition, Time Domain Reflectometer (TDR) analyses were performed to observe the effect of mounting rings on impedance improvements with the help of software. As a result, it has been determined that the support rod rings, which have not been used before in C band helix TWT systems, positively affect the ease of assembly and impedance improvement.

Özet

C bant aralığında çalışan bir heliks (Yavaş Dalga Yapısı SWS) ilerleyen dalga tüpü (TWT) CST yazılımı kullanılarak tasarlanmıştır. Modellemeye dayalı olarak TWT bileşenleri üretildi. Empedans hattını eşleştirmek ve montaj kolaylığı sağlamak için iletken destek çubuk halkaları kullanıldı. Modellemeye göre sinyal kazancı 30 dB olarak belirlendi. Ayrıca yazılım yardımı ile montaj halkalarının empedans iyileştirmelerine etkisini gözlemlemek için Zaman Tanım Alanlı Reflektometre (TDR) analizleri yapılmıştır. Sonuç olarak C bant sarmal TWT sistemlerinde daha önce kullanılmamış olan destek çubuk halkalarının montaj kolaylığını ve empedans iyileştirmesini olumlu yönde etkilediği tespit edilmiştir.
