WiFi Module - Layout Guidelines

Things to remember in creating a PCB trace on RF.

~Do not use right angles in the RF trace, it is better to use 45° bend or radius to change

~ Do not route any signals under the RF trace.

~ It is recommended that you try to use at least 10 mils (0.254mm) traces to route the RF signals. However, due to your PCB stack-up you may have to use layer 3 as your RF ground reference instead of layer 2. To use layer 3 as your RF ground reference you will have to make sure layer 2 is clear of copper.

The clearance on both sides of the
RF trace should be at least
1.5 to 2 times the RF trace width

~ When transitioning from the RF trace to components try to keep the transition smooth. The gray pad is a component pad. And the blue is RF trace.

~ Do not place matching circuits that creates stubs in the RF path.

trace will have stubs with this type of
layout if the shunt elements are not used
