Correct RF trace
• The CPW (coplanar waveguide) design and the microstrip line are both recommended; the
customers can choose either one depending on the PCB stack of their products.
• The RF trace must be isolated with aground beneath it. Other signal traces should be
isolated from the RF trace either by ground plane or ground vias to avoid coupling.
• To minimize the parasitic capacitance related to the corner of the RF trace, the right angle
corner is not recommended.
If the customers have any problem in calculation of trace impedance, please contact AzureWave.
