PIM Chambers from Cuming-Lehman Chambers
Passive Intermodulation (PIM) occurs when two or more signals are present in a passive device, such as a cable, connector, isolator or switch, that exhibits a nonlinear response. These nonlinear characteristics are typically a result of imperfections or material inconsistencies within the device. When multiple frequencies interact within the component, they can generate unwanted signals. These spurious signals, known as intermodulation products, may interfere with the desired communication signals, leading to degradation of signal quality and potentially causing significant issues in telecommunications systems. In demanding environments like aerospace applications, maintaining optimal system performance is critical. Therefore, understanding and minimizing PIM is important for engineers and technicians who aim to enhance system reliability and efficiency.
PIM Testing and Mitigation
PIM can severely impact system performance, especially in high-frequency, high-sensitivity environments. It can:
- Create spurious signals that disrupt communication.
- Lead to data loss, reduced throughput or dropped connections.
- Cause failures in radar and navigation systems.
