nRF24L01+ Noise Figure

[Jim McInttyre]

We use the nRF24L01+ in a dedicated RX mode, and it is preceded by a power splitter, filters and LNA.  In order to run some system calculations, I'd really like to know the approximate NF of the nRF24L01+ (we are running 1 Mbps, if that matters).  I know this is not a guaranteed parameter, I'd just like to be able to come close to optimizing performance  and not add in too much gain ahead of the nRF chip...

Thanks,

Jim

Hi Jim

The NF for the RX chain (LNA, balun loss and match loss plus some internal noise) is ~8 dB.
