Hello! I'm calculating the matching circuit with the antenna for nRF52832, but nowhere can I find the impedance value of the pins of the radio part, can you help me?

Hi Dmitriy,
we do not include any impedance measurements of the antenna pins in the nRF52832 Product Specification. Instead we specify the needed Reference circuitry to match the antenna pins to 50 Ohms. You can find the reference circuitry here in the nRF52832 Product Specification. You'll see 50 Ohm after the L1 inductor, i.e. the line marked RF in the Refenrece circuitry, see attached schematic.
