nRF54Lxx antenna matching & reference layouts

[Nick_RA]

Does anything exist yet? The datasheet only contains a preliminary matching network and says will be available when the chip enters mass production, but nothing is available on the web site. Mouser have stock of the nRF54L15 so it's in production...

Also, the 54L15DK exists on the market but again no schematic or reference layout.

I'm choosing a SoC for a new product - do you consider the 54L series to be mature enough for development?

Thanks

You can find the reference layout for the nRF54L15 here: https://www.nordicsemi.com/Products/nRF54L15/Reference-layout?lang=en#infotabs

Argh I didn't see that!! Just off the bottom of my screen (I clicked documentation)

I just downloaded it - the schematic still says "Preliminary matching network for nRF54L15 Engineering B. Updates should be expected to recommended component values prior to SoC entering mass production."

I notice the grounding of C6 is different from the datasheet...?

This is true for the CSP version, CAAA only as this is not in production yet. The QFN version is final.
