Is it possible to test an external Bluetooth antenna with the nRF52 DK?

Is there any way to test an external PCB o flex antenna with the nrf52 DK? Thanks in advance.

Hi,

The DK has a SWF connector (J1, part number: MM8130-2600) that you can connect to your external antenna. Make sure you antenna is tuned with 50 Ohm impedance.

Thank you for your answer! Does it make sense if I disolder J1 and solder directly the antenna to the pad?

[Hung Bui]

You can do that, but if you want to optimize the antenna performance you would need to tune it.

Perfect, thanks a lot!
