How to Choose 6dB, 10dB, 15dB, or 20dB Couplers
Nov , 29 2025
One of the questions we hear most often from engineers is: “Should I use a 6dB, 10dB, 15dB, or 20dB coupler — and what’s the real difference in coverage?” On paper, these numbers look like simple coupling values. But from more than two decades of manufacturing RF passive components, we know something very clearly: Choosing the wrong coupling value can break your coverage balance, distort the ...

What's the Difference Between a Combiner and a Hybrid?
Dec , 06 2025
In RF system design and engineering projects, "Combiner" and "Hybrid Coupler (or Hybrid Combiner)" are often mentioned, but they are not the same. Their applications and performance characteristics differ significantly. Basic Concepts and Technical Differences Hybrid Coupler (Hybrid Combiner) is typically a four-port device based on coupled lines, transmission line theory, or branch-line / ring st...

Top 10 RF Passive Components for Reliable Wireless Communication
Dec , 27 2025
In every reliable wireless network — whether it’s a DAS inside a hospital, a 5G macro site, or a public safety system — performance does not start with software. It starts with RF passive components. From our perspective as a manufacturer, most network issues we see in the field are not caused by active equipment failure. They are caused by mismatched, underrated, or poorly selected passive compon...

Why Passive RF Loss Still Limits 5G and DAS Performance
Jan , 10 2026
In 5G and large-scale DAS deployments, engineers often focus on radios, baseband units, and antenna patterns. These are visible, measurable, and easy to discuss in meetings. However, in real-world projects, performance limitations are far more often caused by something less obvious: passive RF loss. After working with operators, system integrators, and public safety networks for many years, one th...

Why Is Tapper an Indispensable Passive Component for Indoor Coverage?
Jan , 17 2026
In the field of mobile communication engineering, the success of an Indoor Distribution System (DAS) depends not on the raw power of the signal source, but on the "art of distribution." As 5G transitions toward Sub-6GHz and higher frequency bands, space path loss and feeder attenuation increase drastically. To achieve seamless "carpet-style" coverage in complex skyscrapers or underground facilitie...
