https://devzone.nordicsemi.com/f/nordic-q-a/60262/ti-swra117d-antenna-design-for-nrf52810-kicadHi, New user here, I develop using Kicad and it has an antenna based on the Ti SWRA117D design, which is 2.4GHz. Can I confirm I only need two components (as per reference design) plus this antenna? The alternative TI devices use a lot more inductorsen-USTelligent Community 13Thu, 16 Apr 2020 16:02:27 GMThttps://devzone.nordicsemi.com/thread/245074?ContentTypeID=1Thu, 16 Apr 2020 16:02:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8eed14ff-fc11-4812-8f0d-03754072e185snoopy20<p>It was worth double checking.

The components to the right, L22 and C7 in this design, are specific to the device. Different radios used different numbers of components here.&nbsp;</p> <p>The antenna may or may not need tuning components. The<span>&nbsp;SWRA117D seems to be designed to be 50 ohm when done correctly. So you should be able to place the antenna directly to L44, as you have it now.</span></p><div style="clear:both;"></div>
