Understanding Low PIM in RF Passive Components: Why It Matters
Jul , 17 2025
What is PIM and Why "Low" PIM is Critical? PIM stands for Passive Intermodulation, a form of signal distortion that occurs when two or more high-power RF signals mix within a passive component—such as connectors, cables, power splitters, couplers, or antennas—and create unwanted interference at new frequencies. These new frequencies can degrade system performance, reduce data throughput, and affec...
