Abstract :
This paper presents an experimental technique of the near-field probing of passive intermodulation (PIM) products distribution on microstrip transmission lines. An effective normalization of the probe readings at the intermodulation frequency is proposed and validated by experiment. The main properties of the distributed PIM generation in microstrip lines are deduced from the experimental results.
