Patent ID: 10979117

Abstract:
A radio frequency receiver comprises a plurality of receiving antennas providing a plurality of radio frequency (RF) signals, a first set of phase shifters providing a first set of analog beams from a first set of RF signals in the plurality of RF signals, a second set of phase shifters providing second set of analog beams from a second set of RF signals and a digital beamformer providing final set of beams employing the first set of analog beams and the second set of analog beams. Similarly a radio frequency transmitter comprises a digital beamformer providing a plurality of digital beams, a first set of splitter splitting a first set of digital beams in the plurality of digital beams into first set of analog beams, a second set splitter splitting a second set of digital beams in the plurality of digital beams into second set of analog beams, a first set of phase shifters providing a first set of analog beams, a second set of phase shifters providing second set of analog beams, a set of adder adding the first of analog beams and second set of analog beams to form the set of RF signals.
