The SMA female 4-hole flange mount RF connector<\/strong> with 1.27 mm pin and 8.64 mm hole spacing is designed for solder attachment<\/strong> in compact RF systems requiring stable and repeatable performance. Operating from DC to 18 GHz at 50 \u03a9 impedance<\/strong>, the SMA-KFD-S1 provides reliable electrical connection and mechanical rigidity in high-frequency environments.<\/p>\n Featuring VSWR \u2264 1.08<\/strong> and insertion loss \u2264 0.06 \u221aF(GHz) dB<\/strong>, the SMA-KFD-S1 connector<\/strong> minimizes reflection and transmission losses while ensuring phase stability across broadband applications. The precisely machined 1.27 mm pin guarantees consistent signal integrity in measurement and communication systems.<\/p>\n Constructed from corrosion-resistant stainless steel with gold-plated beryllium copper contacts, the SMA-KFD-S1 RF connector<\/strong> combines high conductivity with excellent mechanical endurance. All materials conform to RoHS and REACH compliance<\/strong> standards, ensuring both performance and environmental responsibility.<\/p>\n The 4-hole flange mount design<\/a> provides secure panel installation and precise connector alignment in amplifiers, transceivers, and microwave modules. Its solder attachment interface delivers a vibration-resistant connection ideal for demanding RF systems.<\/p>\n Mechanc\u2019s SMA connector series<\/a> includes flange-mount, cable-mount, and bulkhead designs for DC\u201318 GHz systems.
