Abstract

　低周波数帯回路にＳＡＷフィルタを設けてインピーダンスの不整合があっても、高周波数帯の通過特性に劣化がない高周波部品の提供を図る。高周波部品は、ハイパスフィルタ（１０２）とローパスフィルタ（１０１）とをアンテナポートに並列に接続したダイプレクサ（１）と、ハイパスフィルタ（１０２）に縦続接続した高周波数帯回路と、ローパスフィルタ（１０１）に縦続接続した低周波数帯回路と、を備え、低周波数帯回路に、インピーダンスの不整合を生じさせるフィルタを接続している。ローパスフィルタ（１０１）は、線路（Ｌｔ１）を備え、この線路（Ｌｔ１）を含む並列共振回路（１０１Ａ）と、線路（Ｌｔ１）を含む直列回路（１０１Ｂ）を構成する。並列共振回路（１０１Ａ）の共振周波数は高周波数帯の送受信信号のトラップ周波数であり、ローパスフィルタ（１０１）の全素子による共振の周波数は、高周波数帯側に生じる不要共振のトラップ周波数である。
