Comment gérer la ligne d'alimentation d'un PCB Bluetooth connecté à une antenne à puce de 2,4 GHz?
I’m making a 4 layer PCB prototype that uses a bluetooth mcu connected to a 2.4GHz chip antenna. I’m thinking about what to do with the feedline, whether it should be buried on one of the middle layers, or left on the top layer. To get a 50 ligne d'ohms, should I choose top layer with 13-mil width or buried miccrostrip with 7-mild width?
