Abstract:
A circuit arrangement for compensating for an attenuation occurring in an antenna signal link between a mobile radio terminal and an antenna has at least one antenna signal amplifier in the antenna signal link and a control unit for adjusting a gain factor. The antenna signal conducted through an associated antenna signal amplifier is amplified or attenuated. The circuit arrangement has a detection unit for detecting an antenna signal power (PM, PA) of the antenna signal in the signal path of the antenna signal link. The control unit is configured for changing the gain factor, detecting a change, changing the transmit power (PM) of the mobile radio terminal, and adapting the gain factor to the coupling attenuation of the antenna signal link in dependence on a detected response of the mobile radio terminal.

Abstract:
A circuit arrangement (1) for compensating for a damping occurring in an antenna line between a mobile radio terminal (2) and an antenna (3), comprising a plurality of partial branches (T1, T2, T3) in each case for assigned transmission services for specific frequency bands, is described. A first partial branch selection switch (S1), on the terminal side at an antenna connection (4) of the circuit arrangement (1), said antenna connection being connectable to the mobile radio terminal (2), is connected to a selected partial branch (T1, T2, T3) depending on the switching position and a second partial branch selection switch (S2), on the antenna side at an antenna connection (5) of the circuit arrangement (1), said antenna connection being connectable to the antenna, is connected to a selected partial branch (T1, T2, T3) depending on the switching position such that a partial branch (T1, T2, T3) selected by the switching position of the partial branch selection switches (S1, S2) is switchable into the signal path between mobile radio terminal (2) and antenna (3). The partial branches (T1, T2, T3) have at least one reception amplifier (EV21, EV22, EV31, EV32, EV33) and/or a transmission amplifier (SV21, SV22, SV31, SV32, SV33). The circuit arrangement (1) has a pulse detection unit (6) for detecting pulse properties of a high-frequency mobile radio signal of a mobile radio terminal (2) that can be connected to the circuit arrangement, and is designed for selecting a partial branch (T1, T2, T3) by driving the first and second partial branch selection switches (S1, S2) depending on the detected pulse properties.
