Zusammenfassung:	To provide a transmission/reception module capable of preventing an increase in insertion loss due to insertion of a switch element.SOLUTION: A plurality of duplexers operate in different bands from each other, and each of them includes a transmission filter and a reception filter. A power amplifier amplifies and outputs signals in pass-bands of the plurality of transmission filters. A transmission line for transmission through which the signals in the pass-bands of the plurality of transmission filters output from the power amplifier are transmitted is connected to the plurality of transmission filters.SELECTED DRAWING: Figure 1 【課題】スイッチ素子を挿入することによる挿入損失の増大を抑制することが可能な送受信モジュールを提供する。【解決手段】複数のデュプレクサが相互に異なるバンドで動作し、各々が送信フィルタと受信フィルタとを含む。パワーアンプが、複数の送信フィルタの通過帯域の信号を増幅して出力する。パワーアンプから出力された複数の送信フィルタの通過帯域の信号が伝送される送信用伝送線路が、複数の送信フィルタに接続されている。【選択図】図１
