[138] RADIO: Spurious emission on GPIO exceeds limits in radiated tests

This anomaly applies to IC Rev. Rev 1, build codes QFAA-B00, QFAB-B00.

It was inherited from the previous IC revision Engineering C.


Spurious emission in RX mode can exceed ETSI limits.


Using the Nordic Development Kit or a product built from reference schematic using GPIO P0.25 and P0.26.


Product does not conform to ETSI requirements.


Use the updated reference schematics and reference layout, version 1.1 or later, available from nRF52 Series > Reference Layout.
