Abstract
An HF combiner includes a housing having a common terminal and n signal line terminals. The n signal line terminals are coupled to the common terminal within the housing via one of n filter paths in each case. A circuit board arrangement is used for outcoupling and separately transmitting low-frequency signals, and includes a common terminal contact and n signal line terminal contacts. Each of the n signal line terminal contacts is electrically connected or connectable to the common terminal contact via one of n bypass lines in each case. For this purpose, a control device controls n signal line switching devices. When an AISG signal is detected at one of the n signal line terminal contacts, the control device is designed to electrically connect the particular one of the n signal line terminal contacts, at which the AISG signal has been detected, to the common terminal contact.
