  • Why Impedance Matching is Important in a Transmission

    Impedance matching is a simple concept: you design a transmission line so that the driver, transmission line, and receiver all have the same impedance value. In modern PCBs, you won't need to worry about parasitic losses that arise from DC resistance in the trace or the substrate conductance, so your impedance will be a real number (resistive).
