To provide a cost-effective low-PIM termination for impedance-matched PIM measurement systems, the design method of the termination using a high-PIM termination and linear attenuator is proposed. The validity of the concept is confirmed using a resistive termination and long semirigid cable as linear attenuator by experiment in 2GHz band. The result shows that a typical microwave resistive termination which has not been used in conventional PIM measurements is available as low-PIM termination using the proposed method. It is demonstrated that the method provides a cost-effective low-PIM termination.
