https://devzone.nordicsemi.com/f/nordic-q-a/127117/clarification-on-nrf54-reference-layout-requirementsHi, We’re currently integrating the nRF54 series into a product we’re developing, and we’re using the reference schematic and layout as our guide. While working through this, a few questions came up that we’d appreciate some clarification on, mainlyen-USTelligent Community 13Mon, 23 Feb 2026 10:27:16 GMThttps://devzone.nordicsemi.com/thread/561806?ContentTypeID=1Mon, 23 Feb 2026 10:27:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4bf606d0-c729-4bdc-8216-8b039a99bb0eSzabolcs<p>Hi Moshe,</p> <p>Generally, the problem is not with Bluetooth not working. Yes, the range will degrade, but for 1-3 meters, even the worst antenna will get the job done. However, if you plan to sell a product that has Bluetooth functionality, you&#39;ll have to certify that with the authorities (e.g. FCC), and an improper layout will probably cause issues with unwanted emissions. So with that in mind, here are the answers:</p> <ol> <li>For the power supply filtering part, this can be OK, but for the matching network, it is highly recommended to use the exact layout with the exact same components, as it is a very sensitive part of the circuit, and modifying it can result in increased harmonic emissions.</li> <li>It might be able to work with a 2-layer design, but&nbsp;we cannot guarantee it.</li> <li>No, the matching network for the chip does not depend on the antenna, as sometimes the unwanted harmonics are not even radiated by the antenna but by the layout and components themselves.</li> <li>You can lower the output power of the chip, this will also decrease the level of unwanted emissions.</li> </ol><div style="clear:both;"></div>
