4.7 PCB Recommendation
This chapter provides a guide for optimizing RF line.
Table 4-7
Recommend RF guide
Not recommend
Recommend
-
RF Signals and PCIE line are not
Isolated and it will cause cross talk.
-
Layer 1
Layer 2
Layer 3
-
RF Signals are not shielded with GND.
There are not GND Via next to the
signal lines.
This Impedance mismatch
causes High insertion loss.
-
RF Signals and too many digital/analog
lines are not isolated
.(Cross talk and
Impedance mismatch)
-
There are line width discontinuity and
Impedance mismatch.
This Impedance
mismatch causes High insertion loss
