How to Reduce Third-Order Intermodulation in Passive RF Components
Mar , 05 2026
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....

Duplexer vs Combiner: Key Differences in RF Communication Systems
Mar , 07 2026
Duplexers and RF Combiners are both used in RF communication systems to manage and transmit signals. Many engineers or system designers sometimes confuse these two devices because they may appear in similar positions within a network architecture. However, in real-world deployments such as 5G networks, DAS systems, and wireless communication infrastructure, they perform very different functions. F...
