Minimizing insertion loss: Why understanding trace width is critical at high frequencies

Material matters An engineer asked me recently about the relationship between trace width and insertion loss while adjusting dielectric height…

The invisible backbone of electronics: Why impedance matters more than you think

beneath the surface of every high-performance circuit lies an unsung champion: Impedance (Z).

Impedance

Impedance

Impedance is an important concept in many different realms of engineering. We often see it in our everyday life, especially…

Your traces aren’t square, but do you need to care?

Your traces aren’t square, but do you need to care?

Yes, you should care about the fact that PCB traces, when actually manufactured, end up having more of a trapezoidal…

Can you make Z higher?

Can you make Z higher?

Simulations should match measurements.  Otherwise, what good are they?  When doing signal integrity simulations, that starts with comprehensive stackup modeling. …

High impedance drives your stackup geometries

High impedance drives your stackup geometries

Anyone that’s ever tried to put 75-ohm video onto a PCB stackup knows how high impedance will drive layer thicknesses. …
