/guides/short-range-guides/b/hardware-and-layout/posts/nrf52805-specific-pcb-guidelinesThis guide will cover the specific areas that must be paid extra attention to when designing a PCB for nRF52805. It is intended as a nRF52805 specific addition to the General PCB design guidelines for nRF52 , which should be read and followed unless oen-USTelligent Community 13 Non-Productionhttps://test-devzone.nordicsemi.com/guides/short-range-guides/b/hardware-and-layout/posts/nrf52805-specific-pcb-guidelinesMon, 24 Aug 2020 21:27:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7ae342b1-be65-44ff-9298-e5576b9f1534user21330<p>There is often confusion as to the nature of the &quot;<span>The RF matching network (L2, C3 and L1)&nbsp;</span>&quot; shown in the reference design.&nbsp; This is NOT a antenna matching network.&nbsp; (See the description of this network in the datasheet)&nbsp; The antenna matching network will need to be added after the&nbsp;<span>&nbsp;RF matching network (L2, C3 and L1)&nbsp;</span>..&nbsp; The number of components will be determined by the antenna type used. For a monopole type antenna a Pi network is normally suggested for ease of tuning.&nbsp; The number of components used and values are determined during tuning / testing.&nbsp; For chip antennas the manufactures application notes should be followed.</p><img src="https://test-devzone.nordicsemi.com/aggbug?PostID=1318&AppID=15&AppType=Weblog&ContentType=0" width="1" height="1">
