Hi Alan

I've taken a look at the schematic and I have a few comments: 

1. C168 should be 1 µF

2. C167 should be 1 µF

3. Depending on the type of antenna, tuning component may be needed, see this whitepaper for more: https://infocenter.nordicsemi.com/pdf/nwp_017.pdf

Else it looks correct.

best regards,

Ketil Aas-Johansen
