Differential co-planar lines

Question asked by mukulratwani on Jun 2, 2014
Latest reply on Jun 16, 2014 by hardevos
Can anybody help me to design differential co-planar lines with the following parameters: 

Differential impedance = 100 ohm.
spacing between ground and signal line around = 50 - 60 um
spacing between signal lines around  = 50-60 um
trace width around  = 30-40 um 

you can use the choice of substrate: 

Er = 3.66, 2.33, 2.20, 6.15, 10

and thickness of PCB around = 0.1 mm 

trace thickness = 0.7 mil or 1.4 mil.

Please reply if anyone can design using these parameter or anyone have idea how to do this.
