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...

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 ...
