Innovative Passive Intermodulation
(PIM) and S-parameter Measurement
Solution with the ENA
Passive intermodulation (PIM) is a form of intermodulation distortion that occurs in passive compo-
nents 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 Key-
