Abstract

　高周波数帯回路に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、低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、高周波数帯回路に、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。ハイパスフィルタ（１０２）は、第１の直列共振回路（１０２Ａ）と、第２の直列共振回路（１０２Ｂ）と、を備え、第１の直列共振回路（１０２Ａ）の共振周波数は低周波数帯の送受信信号のトラップ周波数であり、第２の直列共振回路（１０２Ｂ）の共振周波数は低周波数帯側フィルタの通過特性に生じる不要共振のトラップ周波数である。
