There should be enough ground around the RF line. RF lines Routing prohibit right angles and
sharp angles, trying to trace circular or obtuse angle line.
10
The RF line reference GND should be complete. And avoid high speed lines crossing below it.
11
the GND side of the RF output pin should be non hot welding disk
12
The routing which is RF output PIN to antenna should be isolated from other high-speed
lines. And the routing should be 50Ωimpedance control.
