Hi,
I use the PN7160 I try to follow the AN12810 and AN13219,
I'm not sure about the ground connection, my environement is metalic,grounded and is connected to my board, the middle point of my antenna is also connected to ground.
Do I have to isolate my nano vna power source ground from my board ground ?
Do I have to disconnect the middle point of my antenna for both tunning (antenna and matching) or it is better to connect it to metalic ground to measure antenna/matching impedence?
Thanks.
