3.5mm Female Straight RF Connector for CFS520 Cable \u2013 Model 3.5-KCFS520-1<\/h2>\n

The 3.5 mm female straight cable-mount RF connector<\/strong>, model 3.5-KCFS520-1<\/strong>, is designed for precision broadband applications<\/strong> using the CFS520 ultra-low-loss, phase-stable coaxial cable<\/a>. Operating from DC to 26.5 GHz<\/strong> with 50 \u03a9 impedance<\/strong>, VSWR \u2264 1.15<\/strong>, and insertion loss \u2264 0.06 \u221af dB<\/strong>, it ensures exceptional signal fidelity<\/strong> and low reflection<\/strong> in metrology-grade measurement assemblies<\/strong>. Explore more precision designs within the 3.5 mm connector family<\/a>.<\/p>\n

High-Frequency Precision and Signal Integrity<\/h3>\n

The 3.5-KCFS520-1 connector<\/strong> provides repeatable broadband performance<\/strong> and phase-stable transmission<\/strong> for demanding RF measurement<\/strong> and calibration environments<\/strong>. Its precise interface geometry minimizes VSWR variation<\/strong> and supports consistent impedance matching<\/strong> across the operating frequency range.<\/p>\n

Durable Materials and Stable Contact Design<\/h3>\n

Constructed from passivated stainless steel<\/strong> and equipped with a gold-plated beryllium-copper contact<\/strong>, the 3.5-KCFS520-1<\/strong> ensures low contact resistance<\/strong>, excellent corrosion protection<\/strong>, and mechanical endurance<\/strong> over numerous mating cycles. Its tight tolerance machining<\/strong> preserves signal linearity<\/strong> and return-loss stability<\/strong>. See additional models in RF connectors<\/a>.<\/p>\n

Solder Termination and Mechanical Stability<\/h3>\n

The cable-mount solder termination<\/strong> provides precise dielectric alignment<\/strong> and reliable strain-relief<\/strong>, ensuring stable phase tracking<\/strong> and low insertion loss<\/strong> across extended use. Find similar assembly types in cable-mount connectors<\/a>.<\/p>\n

Optimized Integration with CFS520 Coaxial Cable<\/h3>\n

For consistent signal repeatability<\/strong> and attenuation control<\/strong>, pair the 3.5-KCFS520-1 connector<\/strong> with the CFS520 ultra-low-loss, phase-stable coaxial cable<\/a> to achieve metrology-grade precision<\/strong> and repeatable performance<\/strong> in broadband test and measurement systems<\/strong>.<\/p>\n
