Key Features of the SMA-KFD300 HUADA Coaxial Connector

Frequency Range: The SMA-KFD300 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-KFD300 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-KFD300 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 1.15:1 indicates excellent impedance matching. Lower VSWR values mean less signal reflection and better overall performance.
Impedance: The SMA-KFD300 maintains a consistent 50 Ohms impedance, crucial for minimizing signal loss and maximizing power transfer. It’s the gold standard for RF connectors.
Insulation Resistance: At an impressive 5000 MOhms, the insulation resistance ensures minimal leakage and reliable isolation between conductors. This is essential for maintaining signal integrity.
Termination Style and Body Material: The connector features a 4-hole flange mounting style, making installation straightforward. Its stainless steel body with a passivated finish ensures durability and corrosion resistance.
Center Contact Material: The center contact is made of beryllium copper with a gold finish. This combination provides excellent conductivity and longevity.
Insulation Material: The SMA-KFD300 uses PTFE (polytetrafluoroethylene) insulation, known for its low loss and high-temperature stability. It’s a top choice for RF applications.
Insertion Loss: The insertion loss is remarkably low, adhering to the formula: Insertion Loss≤0.06⋅F(GHz)dB where (F) represents the frequency in GHz.
Outer Contacts Material: Brass outer contacts with gold and nickel finishes strike the right balance between conductivity and cost-effectiveness.
