Description
The 3.5 mm female straight cable-mount RF connector, model 3.5-KCFS520-1, is designed for precision broadband applications using the CFS520 ultra-low-loss, phase-stable coaxial cable. Operating from DC to 26.5 GHz with 50 Ω impedance, VSWR ≤ 1.15, and insertion loss ≤ 0.06 √f dB, it ensures exceptional signal fidelity and low reflection in metrology-grade measurement assemblies. Explore more precision designs within the 3.5 mm connector family.
The 3.5-KCFS520-1 connector provides repeatable broadband performance and phase-stable transmission for demanding RF measurement and calibration environments. Its precise interface geometry minimizes VSWR variation and supports consistent impedance matching across the operating frequency range.
Constructed from passivated stainless steel and equipped with a gold-plated beryllium-copper contact, the 3.5-KCFS520-1 ensures low contact resistance, excellent corrosion protection, and mechanical endurance over numerous mating cycles. Its tight tolerance machining preserves signal linearity and return-loss stability. See additional models in RF connectors.
The cable-mount solder termination provides precise dielectric alignment and reliable strain-relief, ensuring stable phase tracking and low insertion loss across extended use. Find similar assembly types in cable-mount connectors.
For consistent signal repeatability and attenuation control, pair the 3.5-KCFS520-1 connector with the CFS520 ultra-low-loss, phase-stable coaxial cable to achieve metrology-grade precision and repeatable performance in broadband test and measurement systems.
