摘要: | 本論文提出一個新的結構,來實現寬頻的魔術T。分析上先藉由理查轉換,推導出魔術T之電路模型在理查頻域上的等效電路,並將高通原型濾波器的合成法應用於分析此結構上,根據這個方法,設計者得以根據自訂的規格,快速並精確合成出整個魔術T。 A new broadband planar magic-T is presented. By Richard’s transformation, we can derive the equivalent circuit model of the magic-T in Richards’ domain. Then a synthesis method of the high-pass prototype network will be applied to our circuit model. The magic-T can then be exactly synthesized quickly according to the user-defined specifications such as return loss, bandwidth and impedance transformation ratio. |
