Sharing the same antenna with BLE and Wi-fi

[Will Lizardo]

Hi,

When developing a product with the nRF52840 (or 5340) and the nRF7002, would you be able to share best practices about how to share the same 2.4 Ghz antenna e.g. the SRC2W006 from Antenova (2.4/5Ghz antenna).

There's the Bluetooth LE/IEEE 802.15.4 Coexistence guidlines. 

In short you'll need a RF switch for BLE and 2.4GHz Wifi, and a diplexer for 5GHz Wifi. The nRF7002DK's HW reference files has specs for the DK's switches and diplexer. 

And the SW development consist of a bit of configuration, but is otherwise ready to go.
