a. Trace Design Impedance 50R Calculation
Figure 27: RF Trace Impedance Calculation Parameters
b. Trace Design Geometry
It is important to avoid coupling of noise from digital lines to the RF trace
and also to avoid RF signal coupling into power supply or analogue lines.
Therefore, the following RF trace design geometry has been successfully
used on the Telit standalone testboard and should be followed by OEM’s
re-using BlueMod+S50/AP RED/FCC or IC Certifications.
