The invention concerns a circuit arrangement for compensation of attenuation in an antenna lead for a mobile wireless device.The circuit arrangement is suitable for operation in a wireless network, in which the higher or the lower of two frequency ranges defined in one frequency band is used selectively for transmitting and the other frequency range is used for receiving the wireless signals within the one frequency band. It comprises in a corresponding circuit component at least one signal pathway with a power amplifier which is designed as broadband and this pathway is configured for amplifying HF signals to be transmitted; one signal pathway with a low-noise amplifier which is also designed as broadband and this pathway is configured for amplifying HF signals which are received; two filtering and reverse-switching units, each with a frequency filter and a signal-reversing switch on the input and output sides of the two signal pathways of this circuit component; as well as a detection and control unit controlling the signal-reversing switches.HF signals that are received are conducted in the base state of the circuit component provided for the transmission of the respective frequency range, independently of whether they belong to the higher or lower frequency range of the frequency band, always over the low-noise amplifier.
