| 摘要 |
<p>The invention relates to an arrangement for radio frequency signals particularly in a duplex filter summing part comprising a conductive housing (22) and at least one common transmission line (15) for at least two different signals. In order to reduce intermodulation distortion of signals, which arises in the summing part, the housing (22) of the summing part is arranged to function as a ground plane for the transmission line (15) without the ground plane of a printed board or a ground plane otherwise connected to the transmission line (15).</p> |
