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...

How to Judge the Reliability and Stability of RF Passive Components？
Mar , 28 2026
When engineers design the links for Radio Frequency (RF) and microwave systems, they often look at initial technical indicators like insertion loss, isolation, and Voltage Standing Wave Ratio (VSWR). But these nominal values usually only show the component's "peak performance" when it leaves the factory. The real question is: Will these parts still work well after being used in a complicated outdo...

Why Size Is Important in Designing 5G Small Cells
Apr , 11 2026
As 5G networks become more common, it's becoming clear that traditional macro base stations alone aren't enough anymore, especially in cities with high user density. This is where small cells come in. But in real-world deployment, there is one factor that is often overlooked: size. At first glance, size might seem like a minor detail. In reality, it directly impacts how easy equipment is to instal...
