鳍线滤波器的计算机辅助设计及研制

Design and Development of Fin-line Filter by CAD

介绍了鳍线滤波器的设计原理,针对鳍线滤波器难以调节的弱点,运用微波电路CAD技术中的节点导纳法对其频响特性进行分析,从而有效避免了因重复加工造成的浪费。最后着重分析滤波器结构尺寸的误差对其频响特性的影响。这对研制过程具有一定的指导意义。

This paper briefly introduces Fin-Line design theory .With regard do the difficulty in Fin-Line cut-and-try, CAD methods are used to analyze frequency response of the filter. The waste by multi-manufacturing can be avoided. Finally, the paper presents a detailed discussion on the effect to the frequency response caused by the configuration dimension errors. The conclusion can give a meaningful instruction to develop the filter.
