Description
The 3.5 mm male straight cable-mount RF connector, model 3.5-JCFS520-1, is precision-engineered for ultra-low-loss, phase-stable assemblies using the CFS520 coaxial cable. Supporting 50 Ω systems from DC to 26.5 GHz with VSWR ≤ 1.15 and insertion loss ≤ 0.06 √f dB, it ensures stable amplitude and phase performance for laboratory-grade measurements and field calibration setups. See additional precision interfaces within the 3.5 mm connector family.
The 3.5-JCFS520-1 connector provides exceptional impedance consistency and low reflection across broadband frequencies, ensuring repeatable results in vector network analysis and RF instrumentation. Its metrology-grade design supports phase tracking and low attenuation in demanding applications.
Fabricated from passivated stainless steel and fitted with a gold-plated beryllium-copper center contact, the 3.5-JCFS520-1 offers excellent corrosion resistance, low contact resistance, and mechanical robustness. Its tight-tolerance machining minimizes return-loss variation and ensures consistent impedance control under frequent mating. Browse related designs in RF connectors.
The solder-type cable termination enables precise dielectric alignment and shielding continuity, providing mechanical stability and consistent electrical performance across temperature variations. Explore more terminations in cable-mount connectors.
