Hi,

For cascade noise calculations, a NF value of 7 dB is normally used for the CC13x2x devices.

Regarding the SNR, please see: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/873351/cc1312r-bit-error-rate-vs-snr

The customer can refer to Section 8.14 and the figures in Section 8.22.4 the CC1312R Datasheet: https://www.ti.com/lit/swrs210 for measured RX parameters and "PER vs Level vs Frequency" plots (which we specify instead of SNR values).

Regards,
