Which Is Better: Directional Coupler or Tapper?
May , 08 2025
In RF and microwave systems, power distribution is a critical aspect that directly impacts system performance, reliability, and design flexibility. Two of the most commonly used passive components for signal splitting and power monitoring are directional couplers and tappers. While they serve similar purposes in many systems, they differ significantly in structure, application, and performance. Un...

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...
