Custom NRF52 No Antenna Signal

ricewnr

We created our own PCB for the NRF52 with a Johanson chip antenna but no matter what we do, we can't get a signal from the Antenna, not even a weak one to show up on the spectrum analyzer. We verified that the NRF52 chip itself works by running a peripheral example.

Has anyone else run into this problem, can you take a look at our design? We're missing a pi network but we should still see something right?

    The load caps for the crystal have the right values corresponding with the CL value of the crystal, i.e. 12pF. Have you verified that the crystal is properly mounted? Have you tried running an example that uses the external clock instead of the internal? That would be an easy way of checking that the crystal is working properly.
