About RF antenna connector in PCA10040

[Jusang Kim]

Hello,

I am using a nRF52832 DK(PCA10040). I am qurious about the output impedance at RF connector "J1" on the PC board. Does it provide 50 ohm output impedance so we can connect it directly to a RF tester equipment(R&S CMW RF test platform) without any impedance matching circuit ?

Thank you.

Hello Jusang Kim

Yes the connector has an impedance of 50 Ohm and can be connected to a 50 Ohm system without any additional matching.

According to the hardware files for the PCA10040 found here, the connector is the MM8130-2600RA2.

Best regards
