20110217853 | Connection Device for High Frequency Signals Between a Connector and a Transmission Line - A connection device for high frequency signals includes a printed circuit on one external face of which is printed a transmission line and a coaxial connector surface mounted on the printed circuit on the external face. The invention is of particular use for the transmission of radiofrequency signals in the X band, in particular for frequencies from 9 to 10 GHz. The transmission line is connected to the connector by means of a bump contact belonging to the transmission line to which is attached a central core of the connector. The printed circuit comprises at least one internal ground plane parallel to the external face and contributing to the matching of the transmission line. The invention aims to improve the transparency of the transition between the connector and the transmission line. According to the invention, the internal ground plane is perforated by means of a resist facing the bump contact. | 09-08-2011 |
