The SMA-KF-1.5 is a high-precision RF coaxial connector designed for professional RF cable assembly and panel/PCB mounting. Featuring a 2-hole diamond flange mount, SMA female (jack) interface with external thread & inner hole, and full brass gold-plated construction, this crimp & solder type connector delivers ultra-low signal loss, excellent impedance matching, and long-term reliability for high-frequency applications up to 18GHz. It is fully compatible with RG316, RG174, and 0.086" semi-flexible cables (1.5mm outer diameter), making it the ideal choice for RF cable processing, antenna connection, and microwave communication systems.
Key Features
✅
Full Brass Gold-Plated ConstructionMachined from high-purity brass with thick gold plating, the connector provides superior electrical conductivity, low contact resistance, and excellent corrosion/oxidation resistance, ensuring stable signal transmission and long service life in harsh environments.
✅
SMA-KF-1.5 Standard SMA Female InterfaceFully compliant with SMA international standards, featuring an
external thread & inner hole (SMA female jack) design for secure, vibration-resistant mating with SMA male connectors. The standard SMA interface ensures universal compatibility with all SMA-equipped RF devices.
✅
2-Hole Diamond Flange Mount DesignThe compact 2-hole diamond flange enables easy, secure panel or PCB mounting, providing stable mechanical fixation and excellent anti-vibration performance for fixed installations in control cabinets, equipment enclosures, and communication devices.
✅
Dual Crimp & Solder TerminationDesigned for crimping + soldering termination, it creates a dual-secure connection with RG316/RG174 cables, eliminating signal loosening and ensuring consistent RF performance even under mechanical stress or thermal cycling.
✅
50Ω Impedance & High Frequency CompatibilityEngineered for strict 50Ω impedance matching, supporting a wide frequency range from DC to 18GHz with low VSWR (≤1.2) and minimal insertion loss, making it suitable for microwave, 5G, WiFi, and high-speed RF applications.
✅
Industrial-Grade DurabilityHigh-temperature PTFE insulator and brass housing withstand extreme operating temperatures (-65°C to +165°C), mechanical shock, and vibration, meeting the requirements of industrial, aerospace, and defense applications.
