Noncontact PIM Measurement Method Using Partial Impedance-Matching Method

摘要

In this letter, we propose a partial impedance-matching method using a two-strip resonator for noncontact Passive Intermodulation (PIM) measurements using a coaxial tube. It is shown that the strip closer to the inner tube of the coaxial tube is dominant in the observed PIM characteristics while both strips are excited equally. The ideal efficiency of power to each strip is 50, which is a significant improvement in comparison with conventional methods.
