The receiver intermodulation performance certification of the STM32WB55RG test has been passed using n=3 ( the more restrictive configuration ). But the test can also be passed with n=4 or n=5 ( the number which specifies the frequency relation between the wanted signal and the interferers ).

Thanks for your quick reply, is there any educational material on this?
