Dan,
Yes, for a 4 layer stack, with 8 mils spacing, trace thickness for 50 ohms is 13.067 mils. This is similar to what I got from our PCB vendor stackup drawing. Have attached stackup here.
I am confused after reading a few app notes which suggest that for 50 ohm antenna trace you should have...
I do not have much knowledge regarding RF PCB design so my queries would be very basic:sad:
I have a 433MHz RF module on PCB, its RFM69W by HOPERF. PCB that I am using is a 1.6mm 4 layer board. PCB stack up is TOP signal layer, ground plane, power plane, Bottom Signal layer.
I plan to have an...
