A mobile radio compensator (1) comprises an adjustable signal-level amplification means (12a, 12b) and a central detection means (13) in order to detect the signal level of the transmission signals. An adjustment and/or control means (14) can adjust a signal amplification, produced by the signal-level amplification means (12a, 12b), of the transmission signals on the basis of the signal level detected by the detection means (13). A decoupling means (15) comprising at least two decoupling signal paths (15a, 15b, 15c) is provided, wherein the decoupling signal paths (15a, 15b, 15c) are connected to a power adding means (19) of which the output (20) is in turn connected to the detection means (13). The decoupling means (15) comprises a filter means (25, 25a, 25b, 25c) which is arranged on or in the at least two decoupling signal paths (15a, 15b, 15c), wherein the passbands (Δf1, Δf2, Δf3) for each of the at least two decoupling signal paths (15a, 15b, 15c) differ. The decoupling signal paths (15a, 15b, 15c) comprise an adjustable amplification means (30a, 30b, 30c), which are alternately switched on and off by the adjustment and/or control means (14).
