Abstract

　受信側フィルタチップの第１，第２の平衡端子間のアイソレーション特性を改善することが可能とされているデュプレクサを得る。 　積層基板２上に送信側弾性波フィルタ３及び受信側弾性波フィルタ４が実装されており、積層基板２にアンテナ端子とグラウンド電位との間に接続されるコイルが形成されており、受信側弾性波フィルタ４が第１，第２の平衡端子３２，３３に接続されるＩＤＴのグラウンド電位に接続される第１，第２のグラウンドパッド１０，１１を有し、第２のグラウンドパッド１１とコイルとの間の距離が第１のグラウンドパッド１０とコイルとの間の距離よりも長くされており、第２のグラウンドパッド１１を第２のグラウンド端子３５に接続している導電路Ｅのインダクタンス成分が第１のグラウンドパッド１０を第１のグラウンド端子３４に電気的に接続している導電路Ｄのインダクタンス成分よりも小さくされているデュプレクサ１。
