What Does a Directional Coupler Do, and Why Is It Essential in DAS Projects?
Nov , 22 2025
When working on a Distributed Antenna System (DAS), many engineers encounter a familiar headache: the hardware looks fine — antennas, splitters, cables all seem correctly selected — yet the actual coverage still fluctuates. Some areas have excellent signal, while others stubbornly remain weak. Experienced engineers usually check one component first: the Directional Coupler. Although it’s not as in...

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...
