Dear all, who is professionals in RF circuit,

I need you to judge that the guy who has designed this PC board has knowledge of RF circuit design or not ?
This is VHF PCB board @950MHz, the PCB board has 8 layers

I don't know why he routed RF trace at the edge of PCB



should it correctly be routed like that ?,
how did it mange to guarantee of 50-Ohm impedance ?



Any your comments are valuable, Thanks!
 

It is microstrip line. There is some distance to the PCB edge, so the impedance is not significantly affected.
 
In fact, there is not so much Microstrip structure on that PCB.So, it should be ok..
But if the frequency is high enough, changing the Microstrip Line from 1-7-1 may create a problem if the Impedance Matching or other constraints are tight.
We should know the application and if it's possible the schematic.
