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...

What Does a Mismatched Coupled Port Actually Affect in a Directional Coupler?
Jul , 23 2025
Directional couplers are widely used in RF systems for signal sampling, power monitoring, VSWR detection, and PIM testing. While these components are passive by nature, their performance is highly dependent on how each port is terminated—especially the coupled port. In real-world applications, improper termination of the coupled port—either by leaving it open, using poorly matched devices, or low-...
