| 摘要 |
The invention relates to a combiner (1) for electromagnetic waves that are to be sent or received in, for example, a radio base station. The combiner comprises a first unit and at least one second unit, where the first unit comprises a first casing (8), at least two component arrangements, each of which comprises a connector (13) connected to the first casing and designed to make a connection with a device for the transmission of electromagnetic waves, at least one insulator (31) connected to the connector and enclosed in the first casing and an input device which is connected to the insulator (31); at least one screen (36) between the insulators, for screening electromagnetic fields; and at least one circuit board (37) with at least one sensor (41, 42) at least partially housed in the first casing; where the second unit comprises a second casing (14) that defines a cavity (33) for electromagnetic waves for each of the input devices, and at least one output device (5) for tapping electromagnetic waves from at least one of the cavities. The invention also relates to a radio base station and the first unit.
