| 摘要 |
The invention presents a filter combiner, in particular for mobile communications applications, adapted to be connected to an antenna (12), comprising a first directional coupler (13), connected to at least one first filter (15, 15a, 15b), to an antenna branch (12a), to at least one second filter (17, 17a, 17b), and to a first signal branch (20), the combiner also comprising a second directional coupler (21), connected to the at least one first filter (15, 15a, 15b), to a second signal branch (25), and to the at least one second filter (17, 17a, 17b). Further, the first directional coupler (13) is adapted to be connected to the first signal branch (20) via at least one third filter (29, 29a, 29b). |
