To provide multiplexers having hybrid circuits with resonators.SOLUTION: A multiplexer 100 for processing radio-frequency signals includes a signal path 112a-112c implemented between a common node B and multiple nodes A1-A3. Each signal path includes a filter 114a-114c. Each of at least some of the signal paths further includes a resonator 116a-116c coupled with the corresponding filter. A signal path with the resonator provides a sharper notch curve of a radio-frequency signal than a signal path without the resonator.SELECTED DRAWING: Figure 7 【課題】共振器付きハイブリッド回路を有するマルチプレクサを提供する。【解決手段】無線周波数信号を処理するマルチプレクサ１００は、複数のノードＡ１〜Ａ３と、共通ノードＢとの間に実装された信号経路１１２ａ〜１１２ｃとを含む。信号経路はそれぞれフィルタ１１４ａ〜１１４ｃを含む。信号経路の少なくともいくつかそれぞれがさらに、対応フィルタに結合された共振器１１６ａ〜１１６ｃを含む。共振器付きの信号経路が、共振器なしの信号経路よりも鋭いＶ字曲線の無線周波数信号を与える。【選択図】図７
