Good afternoon,
For a beamforming application in the Wi-Fi range, I am planning on using an nRF24L01 to generate the signal.
The signal would later be split into N different signals, and individually attenuated/phase shifted by means of other chips.
As an alternate design concept, I was also conjecturing if I could eliminate the signal split, and use directly N units of nRF24L01, synchronized to generate the same signal and directly connected to the phase shifting chips.
The application is at 2.4GHz, so the N signals should be synchronized to a precision of the order of the picosecond (~1degree of phase shift), or at least the same phase precision of the combined signal split apparatus, which is ~4degrees.
My question is: has anyone ever attempted something similar, or has an idea if said precision is attainable with multiple nRF24L01, and possibly some additional device to help the synchronization?
Thank you in advance and
Best regards
Francesco
