Abstract
Description
図1は、この発明の実施の形態1に係る帯域通過フィルタの帯域阻止フィルタ回路をなす単位回路の構成図である。図1に示すように、単位回路は、コンデンサ1とコイル2の直列回路と、コンデンサ3とコイル4の並列回路とを接続してなり、入力端子5と出力端子6をもつ。
この様に、単位回路15、16のコンデンサの値を変化させることにより、通過帯域を可変することができる。
また、帯域阻止フィルタ回路のコンデンサの値を変化させることにより、通過周波数帯域を変化させることが可能な帯域通過フィルタを得ることができる。
さらに、コンデンサやコイルの代わりにスタブ線路を用いることで、高い周波数において必要となる小さい値のキャパシタンス値やインダクタンス値が実現しやすいものとなる。
