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 affect overall network quality, especially in multi-band and high-density environments.
Low PIM means that a component is specifically designed and manufactured to minimize intermodulation interference, often below –150 dBc or even –161 dBc. In mission-critical networks—such as public safety DAS, 5G base stations, and in-building wireless systems—Low PIM is not a feature. It's a requirement.
PIM is typically caused by:
Poor mechanical contacts (e.g., loose or corroded connectors)
Ferromagnetic materials inside components
Microscopic gaps and inconsistent plating on conductor surfaces
Aging and wear from repeated installation/removal
That’s why high-performance passive components require precision engineering, non-ferrous materials, and strict quality control throughout production.
At Maniron, our Low PIM-rated RF passive components are designed and tested to meet or exceed industry standards, offering:
✔ PIM rating as low as -161 dBc @ 2x20W (typical)
✔ Robust mechanical design for stable and consistent performance
✔ Silver or tri-metal plated connectors for long-term reliability
✔ Independent factory PIM testing with full traceability
✔ Low VSWR and insertion loss, ensuring overall signal integrity
Whether you need Low PIM 3dB hybrid couplers, termination loads, directional couplers, or power splitters, Maniron delivers products you can trust in real-world deployments.
Low PIM components are essential in:
5G and LTE base station deployments (macro and small cells)
In-building Distributed Antenna Systems (DAS)
Public safety and emergency networks
High-speed rail and tunnel coverage systems
Multi-operator or multi-band shared networks
In any environment where multiple RF signals coexist, PIM can be the invisible bottleneck. Using Low PIM components ensures your network performs as intended.
