C168 should be 1 µF</p> <p>2. C167 should be 1 µF</p> <p>3. Depending on the type of antenna, tuning component may be needed, see this whitepaper for more:&nbsp;<a href="https://infocenter.nordicsemi.com/pdf/nwp_017.pdf">https://infocenter.nordicsemi.com/pdf/nwp_017.pdf</a></p> <p></p> <p>Else it looks correct.</p> <p></p> <p>best regards,</p> <p>Ketil Aas-Johansen</p><div style="clear:both;"></div>
