High Frequency PCB Design Guidelines: Stackup, Impedance, Routing and EMI Control
Designing a high frequency PCB is not the same as laying out a standard digital board. Once signals rise above a few hundred MHz, every physical dimension on the board — trace width, dielectric thickness, via geometry, reference plane continuity — starts to affect electrical performance in ways that a Read more
