Reducing Passive Inter-Modulation Passive Inter-Modulation, also known as PIM is a problem that can affect FDD (Frequency Division Duplexing) LTE systems. Explaining the PIM Problem: Passive Inter-Modulation (PIM) products are caused by passive components such as duplexers, connectors, cables, and antennas. These components are nonlinear and create intermodulation products that can leak into the receive […]
