I want to extend BLE range from 200m ~ 500m using FEM. For the first time, I choose SKY66111 but it is not working well because it has only PA module. So I find out new FEM as your adivceen-USTelligent Community 13Tue, 01 Dec 2020 01:09:51 GMThttps://devzone.nordicsemi.com/thread/282564?ContentTypeID=1Tue, 01 Dec 2020 01:09:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:852b6d22-2462-430b-bade-b26876c48386jswcomkr<p>Thank you for reply.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/279154?ContentTypeID=1Tue, 10 Nov 2020 09:13:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a6d2fe0-e8ef-4ff7-8183-7365400298c8JONATHAN LL<p>Hi,<br /><br />Here is a reference documentation for the RFX2411N that you can follow:<br /><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/2047.Nordic-nRF51_5F00_Range_5F00_Extension_5F00_with_5F00_RFaxis-RFX2411N_5F00_Rev2.0.pdf">/cfs-file/__key/communityserver-discussions-components-files/4/2047.Nordic-nRF51_5F00_Range_5F00_Extension_5F00_with_5F00_RFaxis-RFX2411N_5F00_Rev2.0.pdf</a>&nbsp;<br /><br /><br /><br />For the RF out:<br /><br /><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/3527.pastedimage1604998897131v1.png" alt=" " /><br /><br />For the antenna out reference you can see the schematic for component ad layout, to match the 50 ohm.&nbsp;<br />Adding two 0.2pF caps at the start of the filter in you layout&nbsp; should be ok.&nbsp;<br /><br />Otherwise looks ok. maybe contact Skyworks for best guidance on matching network for the FEM.&nbsp;<br />Regards,<br />Jonathan</p><div style="clear:both;"></div>
