hi there,
Im currently studding as a 2nd year at Vishwakarma institute of technology.
I have designed a embedded system around the nrf54L10 for a project but I have gotten stuck on the RF part.
I would like to use a UfL connector to connect a good antenna to the MCU but how to design and calculate the values of the pi filter and rf section are unknown to me if you could provide something like a application note or so documentation on that regard it will be very helpful.
Thank you,
Arnav Badhe
Hello Arnav,
The nRF54L15 datasheet is here and you will find most of the information there: https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/keyfeatures_html5.html
The nRF54L15 DK HW files and guide can be found here: https://www.nordicsemi.com/Products/Development-hardware/nRF54L15-DK/Hardware-files?lang=en#infotabs That's a good place to find the schematic and layout used. Copy it is the recommended way.
There's a general design guidelines for the nRF52 series here: General PCB design guidelines for nRF52 series the same principals applies for nRF54L series as well.
We have a guide on antenna tuning here: https://docs.nordicsemi.com/bundle/nwp_017/resource/nwp_017.pdf
The output of the ANT pin where it says "RF" here is the known 50 Ohm point, 
This is where you would connect your connector.
Best regards
Asbjørn
