This anomaly applies to Revision 1, build codes QFAA-B00.
Symptoms
TX output power deviates from the value specified in the nRF7002 Product Specification.
Conditions
The device is operational in TX mode in 2.4 GHz or 5 GHz band.
Consequences
- For trace codes earlier than 2333xx (year 2023, week 33) with or without a black R sticker on the reel, vacuum bag, and inner box label and nRF Connect SDK version earlier than 2.5.0, the TX output power can vary by up to ±3 dB. The device might operate outside the specified TX EVM limits.
- For trace codes earlier than 2333xx (year 2023, week 33) without a black R sticker on the reel, vacuum bag, and inner box label and nRF Connect SDK version 2.5.0 or later, the TX output power can be up to 3 dB lower than specified.

Workaround
Apply one of the following workarounds:
- Use devices with trace codes earlier than 2333xx (year 2023, week 33) with a black R sticker on the reel, vacuum bag, and inner box label and nRF Connect SDK version 2.5.0 or later.
- Use devices with trace codes 2333xx (year 2023, week 33) or later and nRF Connect SDK version 2.5.0 or later.
