Abstract: A system (1) for beamforming of incoming radio-frequency signals is provided. The system includes at least one digital signal processor, DSP, a plurality of analogue-to-digital converters, ADC, each connected to the at least one DSP. Further, the system comprises a plurality of sample-and-hold, S&H, circuit groups, each comprising a plurality of sample-and-hold circuits additively connected to a respective ADC and a plurality of receiving antenna connections each connected to a respective S&H circuit in each group at one end and each antenna connection connected to a respective antenna. The system is configured to selectively alternate between a plurality of beamforming functionalities, wherein the receiver system is arranged to time-interleave the ADCs and control specific S&H circuits in each S&H group by at least one of time-interleave or disable specific S&H circuits depending on a set beamforming functionality. An associated method (100) is also provided.
