Understanding Low PIM in RF Passive Components: Why It Matters
Jul , 17 2025
What is PIM and Why "Low" PIM is Critical? PIM stands for Passive Intermodulation, a form of signal distortion that occurs when two or more high-power RF signals mix within a passive component—such as connectors, cables, power splitters, couplers, or antennas—and create unwanted interference at new frequencies. These new frequencies can degrade system performance, reduce data throughput, and affec...

Mastering Power Splitter Design: From Principle to Engineering Practice
Oct , 11 2025
In RF and microwave systems, the power splitter is a core passive component responsible for dividing an input signal into multiple outputs with minimal loss and perfect impedance balance. From cellular base stations to satellite networks and RF test systems, the power splitter ensures signal integrity across transmission paths. 1. Basic Principle of Power Splitters A power splitter divides an inpu...

Can't understand high gain rf antenna parameters? How to avoid being misled by suppliers?
Nov , 22 2025
In the telecommunications industry, antennas are a type of product that "look similar but vary greatly in performance." Specification tables often fill an entire page, but people from different industry backgrounds interpret these indicators completely differently. Many engineers and purchasing personnel often encounter a dilemma: suppliers explain things convincingly, but on-site testing reveals ...

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...
