[nRF52810] question about Internal LNA against nearby noise

[Brian Chang]

Hi team,

Our customer use nRF52810 to be an RF dongle.

They meet an question was about the high PER when there was an headset dongle was near nRF52810 as bellowing.

Customer doubt the receiver LNA  gain of the nRF52810 would be affected by the headset dongle (+4dbm TX power) and then the mouse packet would be loss.

They would like to know it is possible to have some of solution  for example  adjusting the LNA gain to overcome the PER/

Thanks

Hi.

Adjusting the LNA gain would only increase the unwanted signal, it would not give you better PER.

If you want to overcome PER you have to use a channel that is not occupied by other traffic.

Best regards,

Andreas
