Filtre passe-bande hélicoïdal RF – 2 pôles / format compact : Série 7S2 | Temwell Corporation

La série Temwell 7S2 regroupe des filtres passe-bande hélicoïdaux RF à 2 pôles conçus pour offrir un format plus compact tout en conservant des performances équivalentes à la série 7H (2 pôles).

Plus de détails

Description

La série Temwell 7S2 regroupe des filtres passe-bande hélicoïdaux RF à 2 pôles conçus pour offrir un format plus compact tout en conservant des performances équivalentes à la série 7H (2 pôles). Elle répond aux architectures RF où l’encombrement est critique sans compromis sur la sélectivité et la stabilité en bande.

Avantages :

  • Compacité : réduction de taille significative par rapport à 7H pour une intégration facilitée.
  • Performances équivalentes à 7H-2POLE sur les indicateurs clés (IL, gabarits d’atténuation, stabilité).
  • Large couverture de fréquences et de bandes passantes pour s’adapter aux normes et canaux.
  • Impédance standard 50 Ω pour une adaptation immédiate au reste de la chaîne RF.

Caractéristiques principales :

  • Fréquence centrale (Fc) : 196 à 1500 MHz.
  • Bande passante (-3 dB) : 2 à 120 MHz.
  • Impédance : 50 Ω.
  • Atténuation hors bande (indicative) : 20 – 30 dB.
  • Topologie : filtre hélicoïdal passe-bande 2 pôles.
  • Format : optimisé « petite taille » pour systèmes denses (low-SWaP).

Applications typiques :

  • Télécommunications : front-ends RF, répéteurs, liaisons point-à-point.
  • Satellite (bord & sol) et stations de base.
  • RADAR et aéronautique : pré-sélection, rejet d’images, co-canaux.
  • Communication minière : environnements sévères nécessitant compacité et fiabilité.

Pourquoi choisir la série Temwell 7S2 :

La 7S2 est la solution idéale lorsqu’il faut gagner de la place tout en conservant le niveau de performance d’une 7H (2 pôles). Elle réduit les contraintes mécaniques et thermiques des équipements compacts, tout en simplifiant l’intégration (50 Ω) et la qualification CEM.
