| 20100134201 | Broadband Directional Coupler with Adjustable Directionality - A directional coupler for the directional transmission of high-frequency signals provides at least three lines and at least three ports. Two lines of the three lines are connected in a conductive manner at least at their ends. A third line is arranged between the two first lines and coupled to the latter in an electromagnetic manner. In this context, the high-frequency signal is transmitted from the third line to the first line and second line. The coupling is implemented via a coupling gap. | 06-03-2010 |
