Review the nRF52832-CIAA impedance matching circuit

We would like to review the following impedance matching circuit: image description

    I think you best option is to register on Noric's MyPage support system

    www.nordicsemi.com/.../register

    And send this as a support request, including you gerber file for the PCB (as I don't think they accept anything other than Altium files)

    I'm now using KiCad, because the cost of Altium is prohibitive on niche products. (Previously I'd been using Eagle)

    BTW. I was a bit surprised about the way you designed your schematic symbol for the nRF52832, as it doesn't look anything like the schematic symbol that Nordic have published

    I know the schematic symbol does not need to look anything like the physical footprint, but as component placement is critical on these devices, I suspect that Nordic made the schematic and physical representation virtually the same to help with the translation of the schematic to the PCB design.
