Balun nRF52

[vidal]

Hello,

Can you share with us the balun of the nRF52 chipset or at least the ZLoad equivalent, that is R + jX value.

The Balun if the nRF52 is a 6-Element Balun or 4-Element Balun?.

Thanks in advance.

Jose.

There is no balun required for nRF52 SoC's. All the antenna connections are single ended.

Only nRF 51 chipsets have balanced antenna connections and require a balun.

I don't think you understand how this blog works. The bulk of the people who provide information on this site do not work for Nordic, including myself. We provide information and support as part of the ecosystem and developer community utilizing Nordic devices. We do this for free in our spare time.

Nordic does however provided significant support on this site and many employees regularly provide answers to posted questions.

With regard to your comment, the post you refer to involves implementing and matching a chip antenna on a custom board.

While it might seem to someone new to RF design that it is a simple matter of hooking up components to make a perfect match...it is not. All designs are highly influenced by their local environment. Epoxy, glass, grounding, vias, trace thickness and width. Even changes as little as a fraction of a millimeter will change a match.
