Hi Jian,

I couldn't find the exact value but usually it is 50 ohm.

Hi Jian,

Following is the response from our team:

The RF FE that connects to 20719's RF port should match to 50-ohm system and usually antenna input is non-50ohm so definitely requires matching to ensure that there is no power loss to the antenna.
