Description
図1は、本実施の形態に係るマルチプレクサ1の外観の一例を示す斜視図である。図2は、本実施の形態に係るマルチプレクサ1の回路図である。なお、図2では、マルチプレクサ1に接続される他の構成(ここでは、アンテナ2及び整合インダクタ3)についても、併せて図示する。これについては、以降の回路図においても同様である。
上記実施の形態では、アンテナ用配線30と整合用配線40とは、合成配線60の略同一の位置に接続されるとした。しかし、アンテナ用配線30と整合用配線40とが接続される位置はこれに限らず、例えば、合成配線60の互いに異なる位置に接続されてもかまわない。以下、実施の形態の変形例1として、このように構成されたマルチプレクサについて説明する。
上記実施の形態では、アンテナ用配線30と整合用配線40とは、パッケージ基板50の平面視において、合成配線60に対して互いに反対側に配置され、かつ、合成配線60と略直交して配置されるとした。また、アンテナ端子Pantと整合端子Pmtcとは、パッケージ基板50の中心CPに対して点対称となる位置に配置されるとした。
上記実施の形態では、マルチプレクサ1は整合インダクタ3等の外付けの整合素子に接続されるとして説明したが、マルチプレクサは整合素子を内蔵してもかまわない。
また、上記実施の形態では、各々がデュプレクサである複数のフィルタ(上記実施の形態では第1フィルタ10及び第2フィルタ20)を備えるマルチプレクサを例に説明した。しかし、複数のフィルタの各々はデュプレクサに限らず、例えば、受信通過帯域でフィルタリングする受信用フィルタであってもかまわない。また、上記実施の形態では、マルチプレクサ1は2つのフィルタ(上記実施の形態では第1フィルタ10及び第2フィルタ20)を備えるとした。しかし、マルチプレクサは複数のフィルタを備えればよく、例えば3つのフィルタを備えてもかまわない。以下、実施の形態の変形例4として、このように構成されたマルチプレクサについて説明する。
以上、本発明の実施の形態及びその変形例に係るマルチプレクサについて説明したが、本発明は、個々の実施の形態及びその変形例には限定されない。本発明の趣旨を逸脱しない限り、当業者が思いつく各種変形を本実施の形態及びその変形例に施したものや、異なる実施の形態及びその変形例における構成要素を組み合わせて構築される形態も、本発明の一つまたは複数の態様の範囲内に含まれてもよい。
