Abstract:
1. Circuit arrangement for compensating an attenuation (Ko, Ka, Ka 1 , Ka 2 ) occurring in an antenna signal connection between a mobile terminal and an antenna with at least one antenna signal amplifier in the antenna signal connection and with a control unit for setting an amplification factor (V) by which the antenna signal routed through an allocated antenna signal amplifier is amplified or attenuated, wherein the circuit arrangement has a detection unit for detecting an antenna signal power (P) of the antenna signal in the signal path of the antenna signal connection, and wherein and that the control unit is configured to adapt the amplification factor (V) at a rate of change slower than the control rate of an antenna signal power control loop between the coupled mobile terminal and a base station of a mobile network with which the mobile terminal has a communication connection, to regulate the transmit power of the mobile terminal at which the antenna signal is emitted by the mobile terminal if the detected antenna signal power (P) lies in a range of a predefined lower limit value (P G1 ) for the detected antenna signal power (P) and a predefined upper limit value (P G2 ) for the detected antenna signal power (P).
