Hi:
My device is nRF52833-QDAA. And I'm totally a beginner in RF.
Right now I'm trying to figure out the component value of the matching network Z1 Z2 Z3 .
How can I do it ?
Thanks in advance!

Hi Ali,
ight now I'm trying to figure out the component value of the matching network Z1 Z2 Z3 .
I dont recommend spending much time trying to solver the "equation" as the theoretical result will likely not be ideal. Best way to do this is to connect to the antenna with a VNA and start adjusting values.

Hi Jonathan,
Thank you for replying. That's very helpful.
Since I need to do PCB manufacturing as soon as possible.
I would like to determine a value of components Z1 Z2 Z3 first(theoretically)
And then adjusting values.
So is there any advise for equation or I just put 0Ω resistor to replace Z1 Z2 Z3?
Best,
Alien
