As factory for RF Passive components, most of our customer always asked us offer the Low PIM passive components, such as Low PIM power splitter, Low pim power tapper, Low PIM directional coupler etc. Why intermodulation is so important in wireless solutions? and how to improve it? Below are 3 tips. 1) Select the appropriate frequency point combination.  The channel point group without th...

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...

In modern wireless communication networks, maintaining signal purity and minimizing interference are crucial for ensuring system reliability and efficiency. One of the most common yet often overlooked sources of signal degradation in RF systems is Passive Intermodulation (PIM). For engineers working in network infrastructure, understanding PIM is not just optional—it’s fundamental. What is Passive...

In the field of mobile communication engineering, the success of an Indoor Distribution System (DAS) depends not on the raw power of the signal source, but on the "art of distribution." As 5G transitions toward Sub-6GHz and higher frequency bands, space path loss and feeder attenuation increase drastically. To achieve seamless "carpet-style" coverage in complex skyscrapers or underground facilitie...

For engineers working in the passive RF component industry, third-order intermodulation (PIM3) is one of the most challenging performance indicators. As communication networks continue to evolve, mobile operators are tightening their requirements for PIM performance. The standard has gradually moved from -140 dBc to stricter levels such as -155 dBc, -160 dBc, -163 dBc, and even -165 dBc....
