Abstract: The proposed disclosure relates to a method (100) and system (1) arranged to provide beamforming of incoming radio-frequency signals, the receiver system (1) comprising at least one digital signal processor, DSP (2), a plurality of analogue-to-digital converters, ADC (3), each connected to the at least one DSP (2). Further the system comprises a plurality of sample-and-hold, S&H, circuit groups (4), each comprising a plurality of sample-and-hold circuits (5) additively connected to a respective ADC (3) and a plurality of receiving antenna connections (6) each connected to a respective S&H circuit (5) in each group (4) at one end and each antenna connection (6) connected to a respective antenna (7). The receiver system (1) is configured to selectively alternate between a plurality of beamforming functionalities, wherein the receiver system (1) is arranged to time-interleave the ADCs (3) and control specific S&H circuits (5) in each S&H group (4) by at least one of time-interleave or disable specific S&H circuits (5) depending on a set beamforming functionality.
