Abstract
Description
まず、回路モジュールの構成について図面を参照しながら説明する。図1は、本発明の一実施形態に係る回路モジュール1の分解斜視図である。図1(a)は、回路モジュール1を上側から見た分解斜視図であり、図1(b)は、回路モジュール1を軸Axを中心として180度回転させた分解斜視図である。図2は、図1の回路モジュール1のブロック図である。図3は、図1の回路モジュール1のA-Aにおける断面構造図である。なお、図1では、主要な電子部品のみが示されており、チップコンデンサやチップインダクタ等の細かな電子部品については省略してある。
outとして、回路モジュール1外に分離して出力すると共に、入力信号RFin_BC0,RFin_BC3を後段のアイソレータ8aに対して出力する。
以下に、アイソレータ8a,8bについて図面を参照しながら説明する。図4は、アイソレータ8aの外観斜視図である。図5は、中心電極35,36が設けられたフェライト32の外観斜視図である。図6は、フェライト32の外観斜視図である。図7は、コアアイソレータ30a,30bの分解斜視図である。
次に、アイソレータ8a,8bの回路構成について図面を参照しながら説明する。図8は、アイソレータ8a,8bの等価回路図である。
ところで、コアアイソレータ30a,30bは、磁束がコアアイソレータ30a,30b外に漏れることを抑制するためのヨークを有していない。そのため、コアアイソレータ30a,30bに高周波信号が流れると、コアアイソレータ30a,30bの周囲には磁束が発生する。そして、コアアイソレータ30a,30bの配置のさせ方によっては、コアアイソレータ30a,30b同士が磁気結合し、アイソレータ8a,8bにおいて所望の特性を得ることができないという問題が発生する。
本実施形態に係る回路モジュール1によれば、ヨークを有していない複数のコアアイソレータ30a,30bが実装された回路モジュール1において、コアアイソレータ30a,30b同士に磁気結合が発生することを抑制できる。より詳細には、回路モジュール1では、コアアイソレータ30a,30bがそれぞれ基板本体14の主面S1,S2上に実装されている。そのため、回路モジュール1では、2つのコアアイソレータが同一の主面に実装されている回路モジュールに比べて、コアアイソレータ30a,30b同士を離して配置することが可能となる。更に、コアアイソレータ30a,30b間に基板本体14が存在するため、直流磁界B1,B2が基板本体14により遮られるようになる。その結果、コアアイソレータ30a,30b同士に磁気結合が発生することが抑制される。
以下に、第1の変形例に係る回路モジュール1aについて図面を参照しながら説明する。図9は、第1の変形例に係る回路モジュール1aの断面構造図である。
以下に、第2の変形例に係る回路モジュール1bについて図面を参照しながら説明する。図10は、第2の変形例に係る回路モジュール1bの断面構造図である。
