Reference design gerbers and correct antenna impedance for nRF52832

[EdT]

I am working on a new design for the nRF52832. I need to match an antenna to the device. My understanding is that the output impedance of the nRF52832 is 53 + J66 for best operation. That would imply that the antenna should look like 53 - j66 ohms, correct to the nRF52832.

The next question is where can I get the gerber files for the reference design? I am really only interested in the area around the antenna. Also, what is the circuit board material and layer thickness for the reference design?

Thanks,

Ed

The impedance that the nRF52832 should see onto the matching network is around 53 -j66 ohm, yes. Note that the matching network also filters the harmonics so you can't omit it by designing an antenna with  the correct impedance. 

For the gerber files, you must look in the Infocenter http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/pdflinks/ref_layout.html?cp=2_5
