Assignee: SAAB AB
Field: Telecommunications (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A radio-frequency (RF) receiver system (1) arranged to provide beamforming of incoming radio-frequency signals, the RF receiver system (1) comprising:
at least one digital signal processor (DSP) (2);
a plurality of analogue-to-digital converters (ADCs) (3), each connected to the at least one (DSP) (2);
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);
wherein the RF receiver system (1) is configured to selectively alternate between a plurality of beamforming functionalities, wherein the RF 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.
