ANA#31

Increase in Rx effective isotropic noise figure when Tx chains are turned ON

Revisions Affected

IWR6843AOP ES1.0, ES2.0

Details

When all the Tx chains are turned ON with full power (0dB Backoff), due to antenna coupling there is a degradation in noise figure of about 2.7dB for Rx2 & Rx4.

Workaround

None. However, the noise figure degradation will be correspondingly lower when TX output power is backed off.
