寬帶天線開關(guān)管頻率特性的理論計(jì)算
THEORETICAL CALCULATION OF BANDPASS CHARACTERISTICS OF WIDE-BAND TR TUBE
-
摘要: 本文從理論上計(jì)算了天線開關(guān)管(又稱TR管)的頻率特性,理論模型是諧振元件的集總參數(shù)的并聯(lián),逐級(jí)進(jìn)行電納的變換。數(shù)值計(jì)算是采取FORTRAN語言程序在向量計(jì)算機(jī)上進(jìn)行的。計(jì)算曲線與實(shí)驗(yàn)結(jié)果比較符合。計(jì)算曲線對(duì)于寬帶TR管的頻帶設(shè)計(jì)提供了有益的參考。

Abstract: The Bandpass characteristics of microwave duplexer TR tube have been calcu-lated theoretically. The theoretical model is that the multiple resonant elements with lumped parameter are shunted, and then the susceptances of these element are transposed step by step. Numeral calculation have been carried out on vector computer with FORTRAN language. Numerical results are in agreement with experimental ones. These calculated results will pro-vide useful rcfcrence for designing wide-band TR tube. -
