Discover the HUADA SMA-KFD477: A Robust RF Coaxial Connector

The HUADA SMA-KFD477 is a high-performance RF coaxial connector designed to meet the demands of critical applications requiring exceptional reliability and signal integrity. Engineered with a 50Ω impedance, this connector ensures optimal signal transmission across a broad frequency spectrum, from 0 to 18 GHz. Its versatile design makes it compatible with both flexible and semi-rigid cables, offering adaptability for a wide range of applications, from industrial and telecommunications to aerospace and scientific research.

Built to withstand harsh operating environments, the SMA-KFD477 can handle temperatures ranging from -65°C to +165°C, making it ideal for demanding applications in various industries. With a 500 mating cycle rating, this connector guarantees consistent performance and reliable connections for extended use, minimizing downtime and maintenance concerns. The low VSWR (Voltage Standing Wave Ratio) ensures minimal signal reflections, preserving signal integrity for critical applications requiring precise signal transmission.

Key Features of the SMA-KFD477 HUADA Coaxial Connector

Impedance: At its core, the SMA-KFD477 maintains a precise impedance of 50Ω, aligning seamlessly with industry standards. This impedance consistency is crucial for optimal signal transmission.
Temperature Range: Operating across a wide temperature spectrum, from a chilly -65 °C to a scorching +165 °C, the SMA-KFD477 remains resilient even in extreme environments. This adaptability ensures performance stability under varying conditions.
Mating Cycles: With a robust design, it withstands up to 500 mating cycles. Frequent connections won’t compromise its durability, making it ideal for applications requiring frequent disconnections and reconnections.
Insulation Resistance: An impressive insulation resistance of 5000 MΩ minimizes signal leakage. This feature is critical for maintaining signal integrity, especially in sensitive systems.
Dielectric Withstanding Voltage: The SMA-KFD477 can handle voltages up to 1000 V without compromising performance. This safety margin ensures reliable operation even during voltage spikes.
Frequency Range:
Flexible Cable: The SMA-KFD477 accommodates frequencies spanning from 0 to 12.4 GHz. Whether you’re dealing with wireless communication or high-frequency applications, this connector delivers.
Semi-rigid Cable: For more demanding scenarios, it supports frequencies up to 18 GHz. This versatility makes it suitable for advanced radar systems, satellite communication, and aerospace instrumentation.
VSWR (Voltage Standing Wave Ratio):
Flexible Cable: The VSWR is precisely 1.15 + 0.02F (where F represents frequency). This low VSWR minimizes signal reflection, ensuring efficient power transfer.
Semi-rigid Cable: Even better, the VSWR for semi-rigid cables is an impressive 1.10 + 0.02F. Low VSWR translates to minimal signal loss and optimal performance.
