Key Features of the SMA-KFD293 HUADA Coaxial Connector

Frequency Range: The SMA-KFD293 operates seamlessly across a wide frequency spectrum, spanning from DC (direct current) up to an impressive 18 GHz. Whether you’re dealing with low-frequency signals or high-speed data, this connector has you covered.
Operating Temperature Range: Designed to withstand extreme conditions, the SMA-KFD293 can brave temperatures as low as -55°C and as high as +165°C. From frigid mountaintops to scorching industrial environments, it maintains its performance and reliability.
Pin Diameter: The connector’s pin diameter measures a precise 0.38 mm, ensuring optimal signal transmission and minimal losses. Precision matters, especially in critical applications.
Voltage Rating (Dielectric Withstanding Voltage): With a robust dielectric design, the SMA-KFD293 can handle up to 500 Vrms (root mean square voltage). This insulation capability prevents electrical breakdown and ensures safe operation.
VSWR (Voltage Standing Wave Ratio): The VSWR of 1.05 + 0.1f (GHz) indicates excellent impedance matching. Lower VSWR values mean less signal reflection and better overall performance.
Insulator Material: The SMA-KFD293 uses either PTFE (polytetrafluoroethylene) or LCP (liquid crystal polymer) as the insulator material. Both options offer low loss and high-temperature stability, making them ideal for RF applications.
Seal Ring: The connector features a silicon rubber seal ring, ensuring reliable sealing and preventing moisture ingress.
Contact Resistance: The center contact has a maximum resistance of 3 mΩ, while the outer contact maintains a resistance of ≤ 2 mΩ. Low contact resistance ensures efficient signal transfer.
Durability: The SMA-KFD293 withstands 500 mating cycles, making it durable for repeated connections and disconnections.
Insulation Resistance: The insulation resistance exceeds 5000 MΩ, ensuring minimal leakage and reliable isolation between conductors.
Insertion Loss: The insertion loss adheres to the formula: Insertion Loss≤0.06⋅f(GHz)dB where (f) represents the frequency in GHz.
Body Material and Finish: The connector’s body and other metal parts are made of brass or stainless steel with gold plating or passivation finish. This combination ensures longevity and corrosion resistance.
