一、前言在设计宽频带带状线结环行器时,必须计算磁化结的输入阻抗。使用不同的计算公式,有时结果相差很大。本文结合8～12.4 GHz带线全频程隔离器的设计进行比较和讨论。已设计成功的该器件批量生产性能为正向损耗a+≤0.5dB,反向损耗a_-≥20dB,驻波系数S≤1.25。采用的铁氧体材料的归一化饱和磁化强度p(?)0.64,相对介电常数ε(?)11.7,有效相对磁导率 I. INTRODUCTION When designing a broadband stripline circulator, the input impedance of the magnetization junction must be calculated. Using different formulas, the results sometimes vary greatly. In this paper, 8 ~ 12.4 GHz band line full-range isolator design for comparison and discussion. The device has been successfully designed mass production performance forward loss a + ≤ 0.5dB, reverse loss a_-≥ 20dB, VSWR S ≤ 1.25. The normalized saturation magnetization p (?) Of the ferrite material used was 0.64, the relative permittivity ε (?) Was 11.7, the effective relative permeability
