Characteristic Impedance Of The Rf Input Line - Sierra Wireless AirPrime XS1110 Product Technical Specification

7: Characteristic Impedance of the RF
Input Line
We used the AppCAD tool to simulate 50 Ω impedance for the RF PCB layout.

Note that:
For multi-layer layouts, you can place a ground layer in the second layer to minimize
the trace width in a specific PCB (such as FR4) and impedance.
For impedance calculation, there is free software available to calculate the trace width
or impedance. Once such software package is:
