Discover the HUADA SMA-KFK RF Coaxial Connector: Precision Engineering for Seamless Connections


This connector isn’t merely a mechanical component; it’s a conduit for invisible symphonies—a harmonious blend of precision engineering and electromagnetic finesse. Picture it as the maestro’s baton, coaxing resonant waves through its 50Ω impedance orchestra.

Key Features of the SMA-KFK HUADA Coaxial Connector


Frequency Range: The SMA-KFK operates from DC (direct current) up to 18.0 GHz, making it suitable for a wide range of applications.
Impedance: The SMA-KFK maintains a consistent 50Ω impedance, ensuring optimal signal transmission efficiency. This impedance match is crucial for minimizing signal reflections and maximizing power transfer.
Temperature Range:
The SMA-KFK thrives in extreme conditions:
Minimum Operating Temperature: It can withstand frigid temperatures as low as -65°C, making it suitable for outdoor and harsh environments.
Maximum Operating Temperature: It remains reliable even at scorching temperatures up to +165°C.
Mating Cycles: The SMA-KFK is designed for durability, with a tested capability of up to 500 mating cycles. Frequent connections won’t compromise its performance. Whether you’re setting up temporary test configurations or deploying long-term installations, this connector can handle the wear and tear.
Insulation Resistance: The connector’s insulation resistance exceeds 5,000 megohms. This high resistance ensures that minimal current leaks across the insulating material, maintaining signal integrity and preventing unwanted losses.
Dielectric Withstanding Voltage: Safety is paramount. The SMA-KFK withstands a test voltage of 1,000 volts rms at sea level. This feature is essential for preventing electrical breakdown and ensuring reliable operation.
Frequency Ranges:
Versatility is a key feature:
With Flexible Cable (0~12.4GHz): Whether you’re working with flexible coaxial cables or patch cords, the SMA-KFK connector covers a broad frequency spectrum. From Wi-Fi applications to microwave communication, it adapts seamlessly.
With Semi-rigid Cable (0~18GHz): For more demanding setups, such as aerospace or defense applications, the SMA-KFK remains stable and performs consistently.
Voltage Standing Wave Ratio (VSWR):
The VSWR ensures minimal signal loss due to reflections:
Flexible Cable VSWR (1.15+0.02F): As the frequency varies, the VSWR remains low, indicating efficient power transfer.
Semi-rigid Cable VSWR (1.10+0.02F): Even in semi-rigid cable assemblies, the SMA-KFK maintains excellent VSWR characteristics.
Mechanical Characteristics:
The SMA-KFK excels in durability:
Connector Durability: Tested for 500 insertions and withdrawal cycles, it’s built to last.
Cable Retention Force: Ensures secure cable attachment, preventing accidental disconnections.
Coupling Nut Retention Force: Maintains coupling integrity during handling and vibrations.
Force to Engage and Disengage: Facilitates smooth mating and unmating, reducing strain on the connector.
Longitudinal Force: Provides stability during use, especially in mobile or dynamic applications.
