C\u00e2ble RF \u00e0 faibles pertes, \u00e0 haute stabilit\u00e9 de phase et d’amplitude<\/h2>\n

Le c\u00e2ble coaxial \u00e0 faibles pertes et phase stable CFA640 est con\u00e7u pour les applications RF et micro-ondes exigeant une pr\u00e9cision de signal reproductible sous contrainte thermique et m\u00e9canique. Fonctionnant jusqu’\u00e0 18 GHz sous une imp\u00e9dance de 50 \u03a9, il offre une stabilit\u00e9 de phase \u2264 \u00b12\u00b0 @ 10 GHz et \u2264 \u00b13\u00b0 @ 18 GHz, avec une variation d’amplitude comprise dans \u00b10,1 dB @ 18 GHz. D\u00e9couvrez d’autres options au sein de la s\u00e9rie CFA \u2013 c\u00e2bles coaxiaux \u00e0 faibles pertes et phase stable<\/a>.<\/p>\n

Construction massive pour une fiabilit\u00e9 \u00e9lectrique durable<\/h3>\n

Le c\u00e2ble CFA640 comporte une \u00e2me massive en cuivre argent\u00e9 de 1,57 mm et un di\u00e9lectrique PTFE basse densit\u00e9, pour une att\u00e9nuation minimale et un contr\u00f4le d’imp\u00e9dance rigoureux. Son double blindage en cuivre argent\u00e9 et sa gaine FEP assurent une suppression des perturbations \u00e9lectromagn\u00e9tiques > 90 dB et une remarquable tenue thermique de \u201355 \u00b0C \u00e0 +165 \u00b0C. Le c\u00e2ble maintient une d\u00e9viation de phase inf\u00e9rieure \u00e0 1400 PPM sur toute la plage de temp\u00e9rature et garantit une stabilit\u00e9 \u00e9lectrique constante en mouvement.<\/p>\n

R\u00e9sistance m\u00e9canique et endurance thermique<\/h3>\n

Avec un diam\u00e8tre ext\u00e9rieur de 6,35 mm et un rayon de courbure minimal de 31 mm (flexion unique) ou 63 mm (flexion r\u00e9p\u00e9t\u00e9e), le c\u00e2ble coaxial \u00e0 faibles pertes CFA640 associe de mani\u00e8re \u00e9quilibr\u00e9e souplesse et durabilit\u00e9, pour une installation fiable et une exploitation de longue dur\u00e9e. Il supporte une puissance moyenne jusqu’\u00e0 1,88 kW @ 300 MHz tout en conservant une faible att\u00e9nuation (0,93 dB\/m @ 18 GHz).
