I changed the trace to 125mils wide and this is how it looks lol. Only problem is that I can't make the trace from the cellular module to the 33uF cap that thick, but it's really really short so I hope that ok?
You have no clearance around the trace, so it will be less than 50 ohms. That microstrip trace width is assuming
a ground plane on the opposite side of the board, and clear space around it top-side.
Normally these things go on 10- to 16-layer boards so that the traces are much thinner for 50 ohms.
This site shows what 50 ohm microstrip looks like on 2-layer 1.6mm pcb, note all the clearance either
side of the strip: http://www.kaislab.com/
Can you go to 1mm or thinner FR4? Or even an impedance-controller substrate (more predictable
impedance, lower RF losses).
