ANT (H23) pin connection

[Jagbir]

I am not using any wireless radio in my application with nRF52840 . What is the best practice to terminate ANT(H23) pin.Shall I connect it to the ground/pull up or leave it un-connected.

Thanks.

Sorry to bother you, but have you solved this problem? If ANT, NFC1 and NFC2 are not used, will the H23 pin be directly grounded? Or is it feasible to ground the H23 pin directly?

As Andreas stated, the NFC pins are internally disconnected when NFC is not used so it doesn't matter if they are grounded or left disconnected on the board. The ANT pin can also be either be left disconnected or grounded as long as the radio is not used.

If you have any more questions please open a new case.

 

Best regards,
