宽带天线开关管频率特性的理论计算
THEORETICAL CALCULATION OF BANDPASS CHARACTERISTICS OF WIDE-BAND TR TUBE
-
摘要: 本文从理论上计算了天线开关管(又称TR管)的频率特性,理论模型是谐振元件的集总参数的并联,逐级进行电纳的变换。数值计算是采取FORTRAN语言程序在向量计算机上进行的。计算曲线与实验结果比较符合。计算曲线对于宽带TR管的频带设计提供了有益的参考。

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. -
