Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for equalizing distortion occurring due to coupling loss in a microwave filter, and to provide a filter manufactured by this method.SOLUTION: The method includes step 401 for designing the initial transfer function of a filter, step 402 for calculating the pole pof the transfer function thus calculated, step 403 for changing the value of the pole pby a quota aso that an asymmetric displacement of the pole is generated along the real axis of a complex plane, and step 404 for calculating a changed transfer function from the initial transfer function and the changed pole p-a. 【課題】マイクロ波フィルタにおいて結合損失によって生じる歪を等化する方法及びこの方法によって製造されるフィルタを提供する。【解決手段】方法は、フィルタの初期伝達関数を設計するステップ４０１と、設計された伝達関数の極ｐｉを算出するステップ４０２と、複素平面の実軸に沿って極の非対称な変位を生成するように、既定の量ａｉによって極ｐｉの値を変更するステップ４０３と、初期伝達関数と変更済みの極ｐｉ−ａｉから、変更済みの伝達関数を算出するステップ４０４と、を有する。【選択図】図４
