I've just spotted what I believe to be an error.
The BoM for the SPIRIT1 RF boards lists the SMA connector as 142-0701-881, on checking this is for 0.8 mm laminate, the RF board measures 1.6 mm.
Your data:

scroll down the page and select STEVAL-IKR002V1 BOM
Scroll down this pdf to the second listing (STEVAL-IKR002V1D)
line 20, refdes J1
This is the part datasheet:
