I'm trying to match the impedance of a RF via from bottom layer to top layer in a 6-layer PCB design. GNSS signal. Unused pad (NFP) removal activated.
The selected via size is 0.9mm pad and 0.5mm drill. No antipad defined so applying copper-to-drill default clearance (0.2mm) at inner ref planes. This results in a 0.9mm ref plane opening.
I'm using Saturn PCB tool and I wonder what data should I fill to get the correct calculation. Internal pad diameter is supposed to be the same as drill diameter? Any help/suggestion will be appreciated.
