What is the input impedance of nrf52840 in different modes

Hi Sasi!

Sorry for the late response!

We don't provide data for this yet, because we haven't measured it yet.
This should however be available in the specification at a later point in time.

Best regards.

Hi, I also need the output impedance of the ANT port in order to get my matching network calculated.

Sometimes, the design has to be slightly different from the reference design, and having no output impedance data makes it impossible to get the maximum output power and thus not the best solution.

Please, this info is important if it isn´t 50 Ohm (which I assume it isn´t).

Best Regards,

Juanjo

Hi.

Please take a look at the documents in the attached folder. You should be able to find the information you need there.
