C\u00e2ble coaxial semi-rigide \u00e0 faibles pertes pour applications RF et micro-ondes \u00e0 18 GHz<\/h2>\n

Le c\u00e2ble coaxial semi-rigide \u00e0 faibles pertes CRG031 est con\u00e7u pour des performances haute fr\u00e9quence stables jusqu’\u00e0 18 GHz. Dot\u00e9 d’une \u00e2me de pr\u00e9cision en acier cuivr\u00e9 argent\u00e9, d’un di\u00e9lectrique PTFE et d’un conducteur ext\u00e9rieur en cuivre recuit sans soudure, ce c\u00e2ble offre d’excellentes performances d’att\u00e9nuation, une grande efficacit\u00e9 de blindage et une forte stabilit\u00e9 dimensionnelle. Avec une remarquable tenue thermique et une bonne rigidit\u00e9 m\u00e9canique, le CRG031 est id\u00e9al pour les modules micro-ondes, les assemblages a\u00e9rospatiaux, les syst\u00e8mes de communication et les applications n\u00e9cessitant des cheminements coaxiaux formables aux caract\u00e9ristiques \u00e9lectriques constantes.<\/p>\n

Performances \u00e9lectriques stables pour une transmission RF de pr\u00e9cision<\/h3>\n

Le c\u00e2ble semi-rigide CRG031 conserve une imp\u00e9dance caract\u00e9ristique de 50 \u03a9 \u00b11,1 \u03a9 et permet une transmission de signal \u00e0 faibles pertes jusqu’\u00e0 sa fr\u00e9quence de fonctionnement de 18 GHz. Une vitesse de propagation de 76 % et une fr\u00e9quence de coupure de 154 GHz garantissent un excellent comportement en haute fr\u00e9quence. L’att\u00e9nuation atteint 8,181 dB\/m \u00e0 18 GHz, ce qui convient aux interconnexions courtes dans les syst\u00e8mes RF de pr\u00e9cision. Avec une efficacit\u00e9 de blindage de 165 dB, le c\u00e2ble offre une isolation exceptionnelle contre les perturbations \u00e9lectromagn\u00e9tiques et assure une int\u00e9grit\u00e9 du signal propre et fiable dans les environnements micro-ondes sensibles.<\/p>\n

Construction rigide en cuivre avec forte endurance thermique<\/h3>\n

Constitu\u00e9 d’un tube de cuivre recuit sans soudure de 0,80 mm, le CRG031 offre une excellente rigidit\u00e9 m\u00e9canique, une bonne stabilit\u00e9 dimensionnelle et la possibilit\u00e9 d’\u00eatre cintr\u00e9 et fa\u00e7onn\u00e9 selon des cheminements fixes sans compromettre les performances \u00e9lectriques. Le c\u00e2ble supporte des temp\u00e9ratures de \u221255 \u00b0C \u00e0 +125 \u00b0C, garantissant sa durabilit\u00e9 dans des conditions d’exploitation s\u00e9v\u00e8res. Avec un poids de seulement 3 g\/m et un rayon de courbure minimal de 4,30 mm, le CRG031 permet un cheminement compact \u00e0 l’int\u00e9rieur des assemblages micro-ondes, des syst\u00e8mes embarqu\u00e9s et des bo\u00eetiers RF miniaturis\u00e9s.<\/p>\n

Applications n\u00e9cessitant un coaxial semi-rigide stable et \u00e0 faibles pertes<\/h3>\n

Le c\u00e2ble coaxial semi-rigide CRG031 convient parfaitement aux modules a\u00e9rospatiaux, aux t\u00eates radar, aux sous-ensembles micro-ondes, \u00e0 l’instrumentation de paillasse et aux syst\u00e8mes RF exigeant de faibles pertes, un blindage \u00e9lev\u00e9 et une formabilit\u00e9 m\u00e9canique stable. Faisant partie de la s\u00e9rie de c\u00e2bles coaxiaux semi-rigides \u00e0 faibles pertes<\/a> de Mechanc, il offre des performances fiables aussi bien en prototypage qu’en production de s\u00e9rie.<\/p>\n

Fabriqu\u00e9 par Mechanc Shanghai Information Technology<\/a>, le c\u00e2ble coaxial semi-rigide CRG031 assure des performances \u00e9lectriques constantes, un excellent blindage et une robuste endurance thermique pour les applications RF et micro-ondes haute fr\u00e9quence jusqu’\u00e0 18 GHz.
