| 摘要 |
<p>The invention relates to a summing member (4) comprising in-connectors for receiving and combining different RF signals and an out-connector for supplying the combined signals further, at least one of the connectors (10) being coaxial and comprising an elongated rod-like inner conductor (11), and an outer conductor (12) surrounding the rod-like inner conductor. To provide an adjustable summing point, said at least one connector (10) comprises a moveable part of low-loss dielectric material or ferrimagnetic material, the part surrounding at least the inner conductor (11) and being moveable lengthwise of the inner conductor (11) so as to adjust the phase angle of a wave reflecting from the connector (10).</p> |
