nRF52833 RX selectivity issue

[Anson_0122]

Hi Team,

Why the RX selectivity performance is different on -MHZ and +MHz?

As I know,  Rx selectivity (or call adjacent channel rejection) performance shall be equal or close on -MHz and +MHz test conditions.

Notice: above picture come from the nRF52833 datasheet

Thanks

The image frequency is at -4 MHz in 2 Mbps mode, so the selectivity becomes affect by this.
