QMA-KFD2 is a flange-mounted QMA female RF coaxial connector designed for equipment panel and microwave module installation. It adopts QMA quick push-lock interface for tool-free rapid connection and disconnection. It supports stable broadband signal transmission up to 6 GHz with VSWR ≤1.25 and low insertion loss. Brass body with Tri-Metal plating delivers excellent shielding performance and superior corrosion resistance, suitable for indoor and outdoor communication equipment. Gold-plated beryllium-copper contact pin features outstanding spring elasticity to maintain consistent electrical contact after repeated mating cycles. Teflon insulator achieves low high-frequency dielectric loss. The flange structure enables firm panel mounting, widely used in wireless communication base stations, RF test equipment and broadband microwave assemblies.
