The Hidden Killer of Next-Gen RF Front-End Performance in 2025 As 5G mmWave base stations, LEO satellite user terminals, and aerospace active phased-array systems push toward 28–40 GHz and even 60 GHz D-band prototypes, two parameters have become non-negotiable: Third-order intermodulation distortion (IP3) must exceed +50 dBm at the antenna port Passive intermodulation (PIM) must...
RO4350B PCB materials are widely deployed in 5G smartphone RF front-end modules because they provide a balanced dielectric profile, low-loss characteristics, and stable RF transmission up to sub-6 GHz and selected mmWave bands. Modern antenna arrays, PA/LPF modules, LNA chains, and tunable impedance networks face stringent constraints in signal integrity, power density, EMI coupling, and...
