Abstract: Differential signal skew compensation techniques for radio frequency interference (RFI) mitigation with no reflection penalty and associated apparatus and methods. A differential pair of signal traces are formed on or in a PCB having at least two changes in direction, with a first signal trace having a first routing path defining a first length and a second signal trace adjacent to the first signal trace including one or more tuning structures that are configured such that the length of the second signal trace matches the first length. Segments of the first signal trace adjacent to the one or more tuning structures of the second signal trace are widened relative to other segments of the first signal trace. The tuning structures may comprise sawtooth structures, accordion structures and other serpentine or meander structures. The solution mitigates RFI without a reflection penalty.
