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

Le c\u00e2ble coaxial semi-flexible \u00e0 faibles pertes CMG250 est con\u00e7u pour une transmission RF et micro-ondes performante jusqu’\u00e0 18 GHz. Dot\u00e9 d’une \u00e2me de grand diam\u00e8tre en cuivre argent\u00e9 ou en acier cuivr\u00e9, d’un di\u00e9lectrique PTFE de pr\u00e9cision et d’un robuste conducteur ext\u00e9rieur tress\u00e9 en cuivre \u00e9tam\u00e9, le CMG250 offre une excellente int\u00e9grit\u00e9 du signal, un blindage performant et une souplesse m\u00e9canique fiable pour les assemblages RF exigeants et les syst\u00e8mes d’instrumentation.<\/p>\n

Performances \u00e9lectriques stables pour l’int\u00e9grit\u00e9 du signal en haute fr\u00e9quence<\/h3>\n

Le c\u00e2ble coaxial CMG250 conserve une imp\u00e9dance caract\u00e9ristique de 50 \u03a9 \u00b11,1 \u03a9 et assure une transmission large bande stable jusqu’\u00e0 sa fr\u00e9quence de fonctionnement de 18 GHz. Une vitesse de propagation de 70 %, un temps de propagation de 4,7 ns\/m et une capacit\u00e9 de 95 pF\/m garantissent un comportement en phase constant sur les trajets RF de pr\u00e9cision. L’att\u00e9nuation reste faible sur toute la bande \u2014 de 0,168 dB\/m \u00e0 500 MHz \u00e0 1,421 dB\/m \u00e0 18 GHz \u2014 assurant une transmission efficace en haute fr\u00e9quence. Une efficacit\u00e9 de blindage sup\u00e9rieure \u00e0 100 dB prot\u00e8ge des perturbations \u00e9lectromagn\u00e9tiques pour une transmission propre et peu distordue.<\/p>\n

Construction semi-flexible robuste avec fiabilit\u00e9 thermique<\/h3>\n

R\u00e9alis\u00e9 avec une solide tresse en cuivre \u00e9tam\u00e9 de 6,20 mm, le CMG250 offre une forte robustesse m\u00e9canique et une formabilit\u00e9 semi-flexible adapt\u00e9e au cheminement dans les modules RF, l’\u00e9lectronique embarqu\u00e9e et les assemblages micro-ondes fortement int\u00e9gr\u00e9s. Un g\u00e9n\u00e9reux rayon de courbure unique de 30,00 mm permet une installation s\u00fbre sans compromettre les performances \u00e9lectriques. Fonctionnant de \u221255 \u00b0C \u00e0 +125 \u00b0C, le c\u00e2ble r\u00e9pond aux exigences thermiques de l’a\u00e9rospatiale, de l’industrie et des environnements de communication avanc\u00e9s.<\/p>\n

Applications exigeant des performances RF souples et \u00e0 faibles pertes<\/h3>\n

Le c\u00e2ble coaxial semi-flexible CMG250 est id\u00e9al pour l’instrumentation 18 GHz, les sous-ensembles radar, les modules de communication, les plateformes de test micro-ondes et les syst\u00e8mes RF exigeant des performances stables avec un cheminement souple. Int\u00e9gr\u00e9 \u00e0 la s\u00e9rie de c\u00e2bles coaxiaux semi-flexibles \u00e0 faibles pertes<\/a> de Mechanc, il offre des caract\u00e9ristiques \u00e9lectriques fiables pour la R&D, la production et l’int\u00e9gration haute fr\u00e9quence.<\/p>\n

Fabriqu\u00e9 par Mechanc Shanghai Information Technology<\/a>, le c\u00e2ble coaxial semi-flexible CMG250 assure une transmission \u00e0 faibles pertes, un blindage performant et une robustesse m\u00e9canique fiable pour les applications RF et micro-ondes jusqu’\u00e0 18 GHz.
