Nrf52832 and RFX2411N connections are not working

[DGY]

The analog circuits 51822 and rfx2411n supplied by the authorities are connected 52832, but the circuit is not working properly.PA and LNA switching has been controlled in the program.Is there any problem with the following circuit?

Hello DGY

The schematics appear to be correct. For a more thorough evaluation of the design I would need to see the layout, or preferably the project files. If your project is confidential you can create a mypage case at nordicsemi.com and refer to this case in your ticket.

You should define what you mean by "working properly". Do you mean no output, no receive, low output power, etc.?

That is a rather complicated antenna match/harmonic filter on the output. You could easily have layout/RF matching issues due to copying a reference design.

Also, the 2411 has a more complicated interface due to the different operating modes and antenna diversity, so code problems could cause issues. The normal PA/LNA assist that is part of the Nordic softdevice isn't designed for such a complicated interface.
