Dear all
To ensure the RF path is designed with an impedance of 50 Ω I calculated the track with 400um. Just before I hand it to layouter, could anyone tell me if I'm on the good side or if it's completely off, what I get?
My Stack up is
CU Top: 35um
FR-4: 0.236mm
CU M1: 70um (needed for high current)
FR-4: 0.868mm
CU M2: 70um (needed for high current)
FR-4: 0.236mm
CU Bottom: 35um
Is the track with of 400um reasonable?
Shall I guard the track with Vias all the way?
Are there any restrictions for the length of that line (I intend to have about 10mm - 20mm)
Any help appreciated. Many thanks
Chris
