Abstract:
1. A device comprising: a communication system transmitter configured to transmit signals via a radio interface in a first frequency band, said communication system transmitter including a variable amplifier configured to amplify signals which are to be transmitted by said communication system transmitter; a receiver configured to receive signals via a radio interface in a second frequency band, said receiver including an attenuator configured to attenuate signals received by said receiver; and at least one processor configured to set an attenuation which is applied by said attenuator to signals received by said receiver to a non-blocking higher value in case said communication system transmitter is transmitting signals with a power level exceeding a certain value, and to set an attenuation which is applied by said attenuator to signals received by said receiver to a lower value in case no signal is transmitted by said communication system transmitter, wherein said higher value is sufficiently high to prevent an evaluation of said attenuated received signals, when said attenuation is set to said higher value, wherein said processor is further configured to set said attenuation which is applied by said attenuator to signals received by said receiver to a value which increases with an increasing amplification factor of an amplification applied by said variable amplifier to signals which are to be transmitted by said communication system transmitter.
