Hi Gavin,

Unfortunately, we do not have this information for the WLCSP yet.

Best regards Håkon

Hi Håkon,

Could you also list the load impedance for the other chip packages? Specifically I am interested in the value for the WLCSP (BGA 62).

Hi Johnson,

The load that the ANT1/ANT2 pins should see has been found to be 6.3+j107 ohms for the QFN48 package of the nRF51x22.

Best regards Håkon
