• Expressnons of the rf impedance of superconducting weak links are obtained by theuse of derived solutions of the nonlinear equation describing a resistive shunt junctionmodel of superconducting weak links. It is shown that the real part of impedance isalways positive in the zeroth current step region and it can be negative in the firstcurrent step region for low power of incident rf radiation. The calculated values of therf impedance in the zeroth and the first current step regiccns from the derivedexpressions of the rf impedance is in good agreement with the calculated ones byAuracher and Van Duzer. The condition for amplification of incident rf radiation isderived.
