I&#39;d like to know if below two lines which high-lighted in RED , Line width should be designed to provide 50 Ω impedance matching characteristics ? &gt;&gt;&gt; Circled by the lighted blue are the lines mentioned above, and looks it doesnen-USTelligent Community 13Wed, 24 Oct 2018 00:44:00 GMThttps://devzone.nordicsemi.com/thread/154192?ContentTypeID=1Wed, 24 Oct 2018 00:44:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:084ba043-ce50-4fe2-892e-f8abfe6c2241Kevin<p>Hi Andreas,</p> <p></p> <p>The answer is very clear for me now, Thank you very much as always!</p> <p>Have a nice day~</p> <p>Kevin.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/154075?ContentTypeID=1Tue, 23 Oct 2018 11:56:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6abde07c-c113-48c3-8427-7d204166eb06Andreas<p>Hi,</p> <p>&nbsp;</p> <p>The line you marked with green in the schematics(between B1 and J1), and yellow in the snip of the layout, should be 50 ohm. The differential lines (red in schematic, turquiose in layout), should be designed as long and as wide as in the <a href="https://www.johansontechnology.com/index.php?option=com_products&amp;id=2450BM14A0002">reference design</a>.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
