Passive Intermodulation (PIM)

Passive Intermodulation (PIM) in High-Frequency PCB Design: Causes and Solutions

When designing RF and microwave systems, engineers pay close attention to intermodulation distortion (IMD), especially in applications where multiple high-power signals are transmitted simultaneously. In passive circuits such as antennas, transmission lines, cables, connectors, filters, and other RF components, a related phenomenon known as Passive Intermodulation (PIM) can become a…
