| titleOfInvention | Miniature controlled-impedance transmission line cable and method of manufacture |
| abstract | Miniature controlled impedance transmission line (1), consisting of a flexible cable provided with conductors placed side by side (10 and 12), used to transmit high frequency signals. The cable is preferably made up of a pair of conductors, each surrounded by respective inner and outer dielectric layers (14, 16, 18 and 20) of different compositions. The interior and exterior dielectric layers apply to each conductor independently of the other conductor, after which the respective exterior dielectric layers (18 and 20) of the two conductors are joined side by side, without modifying the interior dielectric layers (14 and 16). A pair of conductors (2) with minimum cross section is obtained for applications with high density, and with uniform capacitance, also having a stability which cannot be modified under the effect of subsequent manipulations or bends. Preferably, a helical torsion is applied to the conductors, with their internal and external dielectrics, before their connection in order to constitute a pair of conductors with permanent torsion, with capacitance not only uniform and stable but also with uniform and stable twist pitch, by means of which uniform electrical delay characteristics are obtained for the two conductors. |
