Designing High-Frequency PCBs for Signal Integrity

Quick fact

A typical high-speed signal on a PCB travels at about 60-70% the speed of light, and a trace just 1 inch long can behave like a transmission line, causing reflections if the impedance isn't controlled.

Why this is interesting

Ever wondered why your smartphone's Wi-Fi works even though the circuit board is a maze of tiny copper lines? The secret lies in designing those traces so that the signals don't get distorted along the way.
