Abstract
An aspect of the solution herein is directed to a receiver arrangement () including multiple RF-filters (RF, RF, RF) and RF-attenuators (RF-A, RF-A, RF-A), one for each of multiple frequency bands (RX, RX, RX), where each RF-attenuator (RF-A, RF-A, RF-A) is provided with a respective power splitter (PS, PS, PS) that connects the RF-attenuator to an average power detector (Pave), which is configured to monitor an average power of each frequency band, where all frequency bands share a common antenna arrangement (), at least one common LNA () and a common mixer arrangement () configured to mix all frequency bands into a common analog signal, and where a peak power monitor arrangement () is configured to monitor the peak power of the common analog signal, wherein, the receiver arrangement includes a digitizer arrangement () configured to control the gain of each RF-attenuator based on the monitored average power of each band from the average power detector and a detected peak power of the common analog signal from the peak power monitor arrangement.
