I am considering touse the evaluation boards EVAL-ADMV1013 and EVAL-ADMV1014 in a 2x2 MIMO configuration for testing beamforming. Since all information and examples mention just single streams, I wonder what are the possibilities for MIMO.
Is a MIMO configuration supported if the local oscillator is shared between multiple boards? Would it produce a coherent signal?
It should be possible to do this but we recommend that each split of the local oscillator have the same phase delay.
Otherwise the ADMV1017/ADMV1018 has the option to change the phase delay to synchronize…
Otherwise the ADMV1017/ADMV1018 has the option to change the phase delay to synchronize multiple Up down converters. The ADMV1017 & ADMV1018 however is only available via NDA with Analog Devices.
