Abstract
A receiver front end arrangement comprises a radio frequency signal input suitable to be connected to an antenna arrangement, a filter bank of non-overlapping band filters associated with respective band for the multi-band reception, a signal conditioning arrangement connected to the filter bank, and a low-noise amplifier arrangement connected to the signal conditioning arrangement. The low-noise amplifier arrangement comprises a path for each band of bands of the multi-band reception. For each path associated with a band for the multi-band reception the low-noise amplifier arrangement comprises a low-noise amplifier. The respective low-noise amplifier has band pass characteristics, or has a band filter connected where the band filter output has a direct connection to the input of the low-noise amplifier, corresponding to a band of the multi-band reception, respectively. The receiver front end arrangement further comprises a combiner structure arranged to combine the outputs of the respective low-noise amplifier of the paths of the low-noise amplifier arrangement. The signals at the output of the combiner structure have the same frequencies as the corresponding signals at the radio signal input. The signal conditioning arrangement is arranged to condition signals for respective path of the low-noise amplifier arrangement. A multi-band receiver comprising the receiver front end arrangement, and a base station comprising the multi-band receiver are also disclosed.
