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...

How to Avoid PIM Interference in DAS Systems
Aug , 07 2025
In Distributed Antenna Systems (DAS), Passive Intermodulation (PIM) is one of the most common yet overlooked causes of performance degradation. While DAS networks are designed to enhance wireless coverage and capacity, PIM can severely compromise signal quality, leading to dropped calls, reduced data throughput, and costly troubleshooting. This article outlines the practical measures and engineeri...

Optimizing Passive Components for Better 5G DAS Coverage
Aug , 13 2025
With the rapid deployment of 5G in indoor environments, Distributed Antenna Systems (DAS) have become a critical solution to ensure reliable signal coverage. Although passive RF components in DAS are non-powered, their performance directly affects signal transmission quality and overall system stability. Selecting and optimizing these passive components is key to enhancing indoor 5G network covera...

Without Understanding Resonators, You Can’t Truly Understand Filters
Sep , 17 2025
In modern communication systems, the RF filter is one of the most critical passive components. Whether in macro base stations, Distributed Antenna Systems (DAS/IBS), or in environments where 5G and 4G networks coexist, filters play a central role in suppressing interference and ensuring signal quality. However, the true performance of a filter is not determined by its housing or connectors, but by...

Why dB Matters So Much in RF Design
Oct , 18 2025
In the world of RF design, dB (decibel) is more than just a unit—it’s the fundamental language that engineers use to describe gain, loss, power level, and system performance. Without understanding dB, it’s nearly impossible to evaluate or optimize RF components such as antennas, filters, couplers, and power splitters. Understanding the Role of dB The decibel is a logarithmic unit that expresses th...
