Sommaire Capacite lineique C en pF/m La capacite lineique d’un cable coaxial correspond a la propriete du materiau a stocker des charges electriques lorsqu’une difference de potentiel est appliquee entre ses deux conducteurs (conducteur central/blindage). Pour un cable coaxial, il existe une relation permettant de calculer sa capacite lineique en fonction du materiau qui le constitue et de ses dimensions : etant la constante dielectrique (fonction du materiau) ; > d etant le diametre exterieur du conducteur central en mm ; > D etant le diametre sur dielectrique en mm ; Zc etant l’impedance caracteristique...

Sommaire Cette valeur est normalisée à 50 Ω et est indépendante de la fréquence : › εr étant la constante diélectrique relative du matériau ; › d étant le diamètre extérieur du conducteur central en mm ; › D étant le diamètre sur diélectrique en mm. Les tolérances de la valeur de l’impédance caractéristique demandées sont en général très serrées. La majorité des produits Axon’ Cable respectent des tolérances de +/- 1 Ω. À fréquence élevée, la densité de courant est concentrée dans une fine couche située en surface des conducteurs. Cette épaisseur devient de plus en plus mince au fur et à mesure...
