Understanding Microstrip PCB Differential Impedance

Microstrip PCB differential impedance is a measure of the electrical resistance and reactance between two traces in a microstrip circuit that allows the signal to be transmitted in differential mode. A differential pair of traces forms a structure in which the two traces carry equal and opposite signals. Ensuring the correct differential impedance is crucial for optimizing signal integrity and transmission speed, particularly in high-speed data transmission applications. The Calculadora de impedancia diferencial de PCB microstrip simplifies this critical calculation.
