孿生TR開(kāi)關(guān)管相位特性的研究
INVESTIGATION OF THE PHASE PERFORMANCE IN DUAL-TR TUBE
-
摘要: 本文從實(shí)驗(yàn)上研究了平衡天線開(kāi)關(guān)中孿生TR管的兩單管間的相位差對(duì)開(kāi)關(guān)接收損耗和接收駐波比的影響。結(jié)果表明,當(dāng)兩單管間的相位差大于30時(shí),則接收損耗將大于0.5dB,接收駐波比也相應(yīng)增大。文中還將實(shí)驗(yàn)結(jié)果和理論計(jì)算作了比較。 本文還研究了由三級(jí)插入式放電管組成的孿生TR管中各級(jí)管子的相位與整管相位的關(guān)系;結(jié)果表明,這個(gè)關(guān)系近似地符合相位疊加原則。

Abstract: In this paper, the influences of phase difference between two single tubes of dual-TR tube on receiving lose and receiving VSWR in balaneed duplexer are investigated exper-imentally. The experimental results show, if the phase differenee is greater than 30 degrees, then the receiving loss will exceed 0.5 dB and the VSWB will increase correspon-dingly. It shows that the experimental results are comparable with the theoretical calculations.The relation between the phase of individual stage of the three-stage plug-in discharge tube and the phase of the dual-TR tube is investigated. The experimental results indicates that this relation approximately obeys the superposition principle. -
