mmWave RF cables: precision signal integrity
The MMX Series millimeter-wave RF cables utilize a silver-plated copper center conductor and a microporous PTFE dielectric. This structural composition ensures signal integrity across high-frequency bands. The multi-layer shielding architecture, incorporating helical silver-plated copper tape and an outer silver-plated copper braid, achieves a shielding effectiveness exceeding 90 dB. This metric is critical for minimizing electromagnetic interference in sensitive test configurations.
Mechanically, the FEP-jacketed cables support dynamic installation environments with repeated bend radii ranging from 18 mm to 40 mm. They maintain consistent mechanical phase stability under bending stress. Operating reliably in temperature extremes from -55°C to +125°C , the MMX mmWave coaxial cable Series handles peak power levels up to 5 KW, meeting the rigorous demands of advanced mmWave and RF testing applications.
