nRF52832 external antenna schematic configuration

[mercimek]

Hello,

I'm using nRF52832 in a sensor PCB card, and I want it to have an antenna. Now I'm drawing the schematics of the PCB using KiCad, but there is one problem I can't handle. I couldn't find the schematic configuration of external antenna and nRF52832. Could you please help with this situation, I looked up in the datasheets but couldn't see any useful drawing about external antennas.

Thank you

Hi, 

here you go: 



If you are going to use a connector and external antenna with 50 Ohm impedance, one shunt component should be fine for matching the antenna.

Thank you for your reply it really helped. Could you please share me the link of the document that includes this picture?

Hi, 

it's no document including this picture, it's just our reference designs, and then I added the external antenna part to illustrate for you. 

Best regards,
Kaja
