4.4 RF traces note
4.4.1 RF traces layout
 Keep the RF trace from module ant pin to antenna as short as possible
 RF trace should be 50 Ω either on the top layer or in the inner layer
 RF trace should be avoided right angle and sharp angle.
 Put enough GND vias around RF traces.
 RF trace should be far away from other high speed signal lines.
Figure 29: RF trace should be far away from other high speed signal lines
 Avoiding the paroling rout of other system antennas nearly.
 There should be some distance from The GND to the inner conductor of the SMA connector. It
is better to keep out all the layers from inner to the outer conductor.
