A packaged integrated circuit includes an integrated circuit and a package substrate. A trace in the package substrate includes a first portion and a second, high-inductance, portion. The high-inductance portion of the trace is proximate to a port of the integrated circuit and provides a selected inductance operating in cooperation with the capacitance of the port to reduce return loss from the port. The first portion of the trace is part of a transmission line having a characteristic impedance.
