SMA Female 4-Hole Flange Mount Field-Replaceable RF Connector \u2013 Model SMA-KFD14<\/h2>\n

The SMA female 4-hole flange mount RF connector<\/strong> with a 0.3 mm pin and 5.64 mm hole spacing is optimized for miniaturized microwave assemblies, calibration ports, and high-density test modules. The field-replaceable assembly<\/a> simplifies maintenance while maintaining low insertion loss and phase consistency.<\/p>\n

Electrical Performance and Return Loss<\/h3>\n

Featuring 50 \u03a9 impedance<\/strong>, VSWR < 1.08<\/strong>, and insertion loss < 0.06\u221aF(GHz) dB, the SMA-KFD14 connector<\/strong> ensures excellent broadband stability up to 18 GHz. It delivers low reflection and superior repeatability across multiple re-mating cycles. Check additional options in our SMA connector catalog<\/a>.<\/p>\n

Materials and Compliance Standards<\/h3>\n

Made from stainless steel and using gold-plated beryllium copper contacts, the connector combines structural resilience with superior electrical conductivity. It is fully REACH and RoHS compliant<\/strong>, supporting global production standards. See also our flange-mount connector<\/a> range.<\/p>\n

Mechanical Construction and Integration<\/h3>\n

The 4-hole flange mount<\/a> format with 5.64 mm spacing ensures solid panel attachment and accurate alignment in compact system designs. Its geometry is ideal for lightweight yet robust test environments. Visit our RF connector catalog<\/a> for related SMA models.<\/p>\n

Complementary Male Connector<\/h3>\n

Pair with the SMA male 4-hole flange mount RF connector \u2013 Model SMA-JFD14<\/a> to achieve optimized broadband coupling and signal continuity.<\/p>\n","protected":false},"excerpt":{"rendered":"
