A small number of chips have significant deviations in RF consistencyhttps://devzone.nordicsemi.com/f/nordic-q-a/104481/a-small-number-of-chips-have-significant-deviations-in-rf-consistencyHi， We tested the transmission power of the chips and found that a small portion of the chips had a significant deviation in transmission power。Perform exchange testing on good and poor chips, and follow the chip for this issues。 换 mean exchange en-USTelligent Community 13Mon, 09 Oct 2023 11:10:40 GMTRE: A small number of chips have significant deviations in RF consistencyhttps://devzone.nordicsemi.com/thread/449336?ContentTypeID=1Mon, 09 Oct 2023 11:10:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9effa534-6af4-4c47-ac39-6737e040ce35Kenneth<p>Hello,</p> <p>Looking at your measurements I can see the output power is average around ~ -0.75dBm, and you have a chip T5 where you measure about ~-1.4dBm. This is well within specification, we define TX accuracy as within worst case +-4dB:<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html#unique_1071044793">https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html#unique_1071044793</a></p> <p>Kenneth</p><div style="clear:both;"></div>
