Innovative Passive Intermodulation (PIM) and S–parameter Measurement Solution

アプリケーションノート

Passive intermodulation (PIM) is a form of intermodulation distortion that occurs in passive components such as antennas, cables, connectors, or duplexers with two or more high-power input signals. PIM becomes a big issue for modern communication industry. PIM from these passive components in the transmitter path falls in to the receiver path; thus the unwanted signals can increase the noise level of the receiver path that degrades quality of the wireless communication system. In order to comply with the regulations, PIM of passive components test becomes more important nowadays.

 

This application note introduces the test system that combines PIM and S-parameter measurements of passive components by using the vector network analyzer (VNA). The innovative solution with Keysight E5072A ENA Series Network Analyzer1 is introduced in the document that provides Fast, Flexible and Accurate measurement capabilities. It is a higher-performance and cost-effective solution that can replace the conventional PIM test solutions.
