Key Features of the SMA-KFD399 HUADA Coaxial Connector

Frequency Range: The SMA-KFD399 operates in the frequency range from DC (direct current) to 18.0 GHz. This wide frequency coverage makes it suitable for various applications, including high-frequency systems.
Impedance (50Ω): The 50Ω impedance ensures efficient signal transmission. It matches the characteristic impedance of many RF systems, minimizing signal reflections and losses.
Temperature Range:
The connector can withstand extreme temperatures: Minimum Operating Temperature: -65°C, Maximum Operating Temperature: +165°C. Whether in frigid cold or scorching heat, the SMA-KFD399 remains reliable.
Mating Cycles (500): The robust design allows for 500 mating cycles without compromising performance. This durability ensures longevity and ease of use during installations and maintenance.
Insulation Resistance (5000 MΩ): With an insulation resistance of 5,000 megohms, the connector maintains electrical integrity even in challenging environments.
Dielectric Withstanding Voltage (1000 V): The connector can handle a dielectric voltage of 1000 volts. This safety feature protects against electrical breakdown.
Frequency Ranges:
Flexible Cable: Covers the range from 0 to 12.4 GHz. Ideal for applications requiring flexibility.
Semi-rigid: Operates from 0 to 18 GHz. Suitable for stable, high-frequency connections.
VSWR (Voltage Standing Wave Ratio):
The VSWR is a critical parameter for signal quality. For the SMA-KFD399:
Flexible Cable VSWR: Approximately 1.15 + 0.02F, where F represents the frequency in GHz.
Semi-rigid VSWR: Approximately 1.10 + 0.02F.
Lower VSWR values indicate better signal performance.
