Abstract
An aspect of the solution herein is directed to a receiver arrangement (100) including multiple RF-filters (RF1, RF2, RF3) and RF-attenuators (RF-A1, RF-A2, RF-A3), one for each of multiple frequency bands (RX1, RX2, RX3), where each RF-attenuator (RF-A1, RF-A2, RF-A3) is provided with a respective power splitter (PS1, PS2, PS3) 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 (110), at least one common LNA (112, 112a, 112b) and a common mixer arrangement (114) configured to mix all frequency bands into a common analog signal, and where a peak power monitor arrangement (201) is configured to monitor the peak power of the common analog signal, wherein, the receiver arrangement includes a digitizer arrangement (200) 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.
