The conductance through a smooth potential barrier in a narrow quantum wire is shown to be quantized. The study of this simple model demonstrates that there are two essential elements for such conductance quantizations in the ballistic regime: a quantized energy spectrum and a nearly-classical transmission or reflection through the potential barrier. In some sense the quantized conductance steps can be viewed as a spetrometer of the quantum wire.
