nRF52840 DK Alternate Antenna

[hkartadi]

Hi,

I would like to use higher dBi antenna instead of the DK pcb antenna. Can I say the pi-network before J1 (measurement point) probe is 50ohm? Hence I can just remove the J1, solder u.FL connector on that location?

Thanks

On PCA10040 (nRF52-DK), C3 and L1 match the nRF52832 to 50 Ohm. The connector, J1, is placed in the 50 Ohm reference point. The matching network for the antenna consists of C15.
