Without Understanding Resonators, You Can’t Truly Understand Filters
Sep , 17 2025
In modern communication systems, the RF filter is one of the most critical passive components. Whether in macro base stations, Distributed Antenna Systems (DAS/IBS), or in environments where 5G and 4G networks coexist, filters play a central role in suppressing interference and ensuring signal quality. However, the true performance of a filter is not determined by its housing or connectors, but by...

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...
