Hello
I have UMTS<E EVB KIT.
Look at the picture. This is a photo of board with BG96 from this KIT.
The width of the track which connect UFL and BG96 ANT_MAIN pin is less than 1mm.
In according with this:
the track width should be 3mm width, then impedance is 50Ω.
Why the KITs antenna trace is so thin?
