Figure 1: Changing parameters will change the value of your target impedances. ( Source: Saturn PCB Design) 38 DESIGN007 MAGAZINE I APRIL 2025 Methods for applying each of these tools in your PCB design are available for all design- ers. en download a tool such as Saturn's free PCB Toolkit and see how switching to different parameters in the "differential pairs/ XTALK" tab (Figure 1) will change the values of your target impedances. is will get you in the ballpark of creating a good RF design. Now the tough part comes into play: manufacturing. • Vias in pads: Placing vias in the compo- nent pads ends up creating problems for assembly and added cost at fabrication to fill the vias. › One solution is to extend the component pad by using a trace as wide as the pad (called "strapping") for enough distance Cherie Liston
