HUADA SMA-KFD309: Reliable RF Coaxial Connector for Critical Applications

The HUADA SMA-KFD309 RF coaxial connector is a premium choice for engineers and technicians seeking reliable performance and high-quality connectivity in their RF systems. This robust connector is designed to withstand demanding conditions and deliver superior signal integrity across a broad frequency range, making it a perfect choice for critical RF applications.

Built for longevity, the SMA-KFD309 is capable of handling 500 mating cycles without compromising performance, ensuring long-term reliability and consistent connection quality. This is critical for applications where frequent connections and disconnections are necessary. Furthermore, its wide operating temperature range from -65°C to +165°C makes it suitable for both indoor and outdoor installations, even in environments with extreme temperature fluctuations.

This connector handles frequencies up to 12.4 GHz with flexible cables and up to 18 GHz with semi-rigid cables, making it ideal for high-speed data transmission, wireless communications, and other demanding RF applications. Its low VSWR (Voltage Standing Wave Ratio) of 1.15+0.02F for flexible cables and 1.10+0.02F for semi-rigid cables ensures minimal signal loss and excellent signal integrity, crucial for maintaining optimal signal quality.

The SMA-KFD309 excels with its 5000 MΩ insulation resistance and 1000V dielectric withstanding voltage, providing superior signal isolation and protection against high voltage conditions. This ensures reliable operation and prevents signal interference, even in challenging environments where high voltage transients are a concern.

Key Features of the SMA-KFD309 HUADA Coaxial Connector

Connector Type: SMA (Subminiature A) - This is a common RF connector known for its compact size, robust construction, and reliable performance.
Impedance: SMA connectors typically have an impedance of 50Ω. This is standard for RF applications, ensuring efficient signal transmission.
Frequency Range: The frequency range of an SMA connector depends on factors like the connector design, the type of cable used, and the overall RF system configuration. They are often used in applications with frequencies ranging from DC to over 26 GHz.
Operating Temperature: SMA connectors are designed to operate within a wide temperature range, typically from -65°C to +165°C. This makes them suitable for various environments, including harsh conditions.
Mating Cycles: The number of mating cycles an SMA connector can handle varies depending on the connector's construction and quality. A higher mating cycle rating indicates that the connector can be connected and disconnected repeatedly without significant degradation in performance.
Insulation Resistance: High insulation resistance is crucial for RF connectors to prevent signal leakage and ensure proper electrical isolation.
Dielectric Withstanding Voltage: This specification indicates the maximum voltage that the connector can withstand without breaking down.
