DC-18GHz SMA-KFD197 SMA Female 4 Hole Flange 12.7*12.7mm Connector
SMA-KFD197 is a high-performance, 50Ω RF interconnect featuring a 4-hole flange mount and SMA female (jack) interface, engineered for DC–18 GHz microwave and RF systems. Precision-machined from brass with nickel/gold plating, beryllium copper gold-plated contacts, and PTFE insulation, it delivers low VSWR (≤1.10+0.02F), ultra-low insertion loss, and exceptional shielding. Built to MIL-C-39012 standards, it offers rugged durability, 500+ mating cycles, and operates reliably from -65°C to +165°C. Compact, vibration-resistant, ideal for PCB/equipment panel mounting in aerospace, defense, 5G, satcom, test & measurement, and industrial RF systems.
