The embodiments of the present invention provide a non-contact data connection that is adaptable to transmit data across an air gap. The data connection includes a first substrate (706) and a loosely coupled wide band pulse transformer for transmitting data over an air gap (820) separating a primary- winding (704) from a secondary winding (714) of the transformer. The primary winding of the transformer includes at least two planar windings formed in parallel planes upon and/or within the first substrate for facilitating a neutralization of transmission line resonances due to distributed capacitance and inductance of the planar windings.

Les modes de réalisation de la présente invention concernent une connexion de données sans contact qui est adaptable pour la transmission de données à travers un entrefer. La connexion de données comporte un premier substrat et un transformateur d'impulsions en large bande à couplage lâche pour la transmission de données sur un entrefer séparant un enroulement primaire d'un enroulement secondaire du transformateur. L'enroulement primaire du transformateur comporte au moins deux enroulements plats formés dans des plans parallèles sur et/ou dans le premier substrat pour faciliter une neutralisation de résonances de lignes de transmission dues à une capacité et une inductance réparties des enroulements plats.
