nRF5340 - sensitivity and ADDR0

[Salas]

Hi support team,

It is an old question but we would like to understand why

"Typical sensitivity applies when ADDR0 is used for receiver address correlation. When ADDR[1...7] are used for receiver address correlation, the typical sensitivity for this mode is degraded by 3 dB"

Hi Salas,

The nRF52/53 has two demodulators, one is called by the designers as "hypermode" and is used to get better sensitivity. This demodulator is only available on pipe0. I don't have any more details for you, and there may also be some design secrets they want to not share. I think "hypermode" use some "tricks" to find the address in noise.

Best regards,
Kenneth
