C\u00e2ble RF semi-rigide \u00e0 faibles pertes, forte puissance et efficacit\u00e9 de blindage<\/h2>\n

Le c\u00e2ble coaxial semi-rigide \u00e0 faibles pertes CRG250 est con\u00e7u pour les syst\u00e8mes de transmission RF et micro-ondes de forte puissance exigeant un blindage exceptionnel et une grande stabilit\u00e9 structurelle. Fonctionnant jusqu’\u00e0 18 GHz sous une imp\u00e9dance de 50 \u03a9, il assure un contr\u00f4le d’imp\u00e9dance pr\u00e9cis et une faible att\u00e9nuation pour les syst\u00e8mes de test, de radar et de communication. D\u00e9couvrez la s\u00e9rie CRG \u2013 c\u00e2bles coaxiaux semi-rigides \u00e0 faibles pertes<\/a> pour d’autres diam\u00e8tres et plages de fr\u00e9quences.<\/p>\n

Tube de cuivre recuit sans soudure et conducteur argent\u00e9<\/h3>\n

Le c\u00e2ble CRG250 int\u00e8gre une \u00e2me en cuivre argent\u00e9 de 1,78 mm, un di\u00e9lectrique PTFE et un conducteur ext\u00e9rieur en cuivre recuit sans soudure de 6,35 mm, rev\u00eatu d’un alliage ternaire r\u00e9sistant \u00e0 la corrosion. Cette structure m\u00e9tallique robuste offre une efficacit\u00e9 de blindage >165 dB et des caract\u00e9ristiques de phase stables sous contrainte m\u00e9canique, garantissant une fiabilit\u00e9 durable dans les installations fixes.<\/p>\n

Faible att\u00e9nuation et forte tenue en puissance<\/h3>\n

Avec une att\u00e9nuation aussi faible que 0,099 dB\/m @ 300 MHz et 0,862 dB\/m @ 18 GHz, le CRG250 supporte une puissance moyenne jusqu’\u00e0 1,53 kW @ 300 MHz et 0,175 kW @ 18 GHz. Sa vitesse de propagation de 76 % et son rayon de courbure minimal de 32 mm permettent un cheminement efficace dans les assemblages de forte puissance sans compromettre les performances.<\/p>\n

Large plage de temp\u00e9ratures et int\u00e9grit\u00e9 m\u00e9canique<\/h3>\n

Con\u00e7u pour les environnements extr\u00eames, le CRG250 conserve sa stabilit\u00e9 \u00e9lectrique et sa r\u00e9sistance m\u00e9canique de \u201355 \u00b0C \u00e0 +250 \u00b0C. La structure en cuivre semi-rigide emp\u00eache toute d\u00e9formation sous l’effet des vibrations ou de la chaleur, garantissant une transmission RF fiable dans les applications de laboratoire, a\u00e9rospatiales et de d\u00e9fense.<\/p>\n
