This is my reference to other people's circuit to design
Is this way feasible?
Or is there a document that can be referred to?
I need meanwhile used BLE and 2.4G in nRF52810
The uploaded diagram looks correct; the PA/LNA should be placed in the 50 Ohm reference piont and each antenna need a matching network.
Regarding the RFX2411N, I would recommend you to check if the RFXN2411N requires some more components in the RF path for filtering. Some PA/LNAs require that.
OK，thank you for your answer.
