How Passive RF Components Shape Real-World 5G Network Performance
Jan , 24 2026
When operators design 5G networks, most attention goes to radios, spectrum, and software. But once a system leaves the lab and enters real buildings, tunnels, ships, and macro sites, performance is often limited by something far less visible: the passive RF layer. From Maniron’s manufacturing experience, we see the same pattern repeatedly: active equipment defines theoretical capacity, while passi...

Low PIM and Low Insertion Loss: Key Metrics That Define Real RF System Performance
Feb , 09 2026
In modern wireless systems such as 5G, DAS (Distributed Antenna Systems), private networks, SATCOM, and public safety communications, engineers often focus on baseband units, RF modules, spectrum resources, and algorithms. However, once a system is deployed in real environments — office buildings, airports, tunnels, ships, or macro sites — the actual performance ceiling is usually determined by a ...

How to Reduce Third-Order Intermodulation in Passive RF Components
Mar , 05 2026
For engineers working in the passive RF component industry, third-order intermodulation (PIM3) is one of the most challenging performance indicators. As communication networks continue to evolve, mobile operators are tightening their requirements for PIM performance. The standard has gradually moved from -140 dBc to stricter levels such as -155 dBc, -160 dBc, -163 dBc, and even -165 dBc. With more...

What Is the Coupling of a Directional Coupler and How to Choose the Right Value?
Mar , 14 2026
In modern wireless communication and RF systems, directional couplers are one of the most commonly used passive components. Whether in base stations, DAS systems, or testing and monitoring setups, couplers act as "signal splitters" that help engineers control and measure signals efficiently. Understanding the coupling factor and how to select the appropriate coupling value is fundamental for desig...
