| 摘 要： | 提出了一种适用于ＨＦ／ＶＨＦ频段、结构简单的集总参数正文耦合器，导出了元件参数的公式。将两个正交耦合器用一对带状传输线级联起来，可构成一个适用于ＨＦ／ＶＨＦ频段的宽频带正交耦合器。并以３０ＭＨｚ为例，介绍了这种耦合器的设计方法，用计算机辅助分析得出的频率特性与理论分析完全一致。

| Abstract: | This article presents a simple quadrature coupler for HF/VHF consisting oflumped elements,derives a set of formulas for calculating element parameters.Using two ofthese quadrature couplers cascaded by a pair of strip tranmission lines,a wideband quadra-ture coupler for HF/VHF can be constructed.Taking 30MHz as an example,the use of thisdesign method is demonstrated.The freqency characteristics obtained by computer aidedanalysis are consistent with the theoretied prediction. |
