(JA) 帯域通過フィルタ及びその制御方法
Abstract: front page image
(EN)Provided is a band-pass filter which allows the bandwidth of a pass band to be easily changed. This band-pass filter (1B) is provided with: a housing (11); a plurality of resonant plates (12) housed in the housing (11); a first coupling conductor (15) connecting adjacent two of the resonant plates (12); and a second coupling conductor (16) disposed at a position acting on a coupling coefficient between the adjacent two of the resonant plates (12), wherein a distance between the resonant plate (12) and the second coupling conductor (16) is changeable.
(FR)La présente invention concerne un filtre passe-bande qui permet de modifier aisément la bande passante d'un filtre passe-bande. Ce filtre passe-bande (1B) est pourvu de : un boîtier (11) ; une pluralité de plaques résonantes (12) logées dans le boîtier (11) ; un premier conducteur de couplage (15) reliant deux plaques résonantes adjacentes (12) ; et un deuxième conducteur de couplage (16) disposé à une position agissant sur un coefficient de couplage entre les deux plaques résonantes adjacentes (12), une distance entre la plaque résonnante (12) et le deuxième conducteur de couplage (16) étant modifiable.
(JA)通過帯域の帯域幅を容易に変更することができる帯域通過フィルタが提供される。本発明にかかる帯域通過フィルタ(1B)は、筐体(11)と、筐体(11)に収納された複数の共振板(12)と、隣接する2つの共振板(12)同士を接続する第1の結合導体(15)と、隣接する2つの共振板(12)間の結合係数に作用する位置に配置された第2の結合導体(16)と、を備え、共振板(12)と第2の結合導体(16)との間の距離が変更可能である。
