Key Features of the SMA-KFD177 HUADA Coaxial Connector

Connector Type: SMA (Subminiature A) - This is a standard RF connector type.
Impedance: 50Ω - This is the standard impedance for most RF applications, ensuring efficient signal transmission.
Frequency Range:
With Flexible Cable: 0~12.4GHz - This indicates that the connector can handle frequencies up to 12.4 GHz when used with flexible coaxial cables.
With Semi-rigid Cable: 0~18GHz - This indicates that the connector can handle frequencies up to 18 GHz when used with semi-rigid coaxial cables.
Important Note: The frequency range of the connector itself is typically much higher. The limiting factor is the type of cable used, as flexible cables have higher losses at higher frequencies.
Operating Temperature: -65°C to +165°C. This wide range indicates that the connector can operate in a wide variety of environments, including extreme temperatures.
Mating Cycles: 500 cycles. This indicates the number of times the connector can be mated and unmated without significant degradation in performance.
Insulation Resistance: 5000 MΩ. This high value indicates that the connector provides excellent electrical isolation, preventing signal leakage and interference.
Dielectric Withstanding Voltage: 1000V. This indicates that the connector can withstand high voltage without breaking down, ensuring safety and reliability.
VSWR (Voltage Standing Wave Ratio):
With Flexible Cable: 1.15+0.02F - This indicates a low VSWR, meaning that the connector reflects very little of the signal back, ensuring efficient signal transmission.
With Semi-Rigid Cable: 1.10+0.02F - This indicates an even lower VSWR than with flexible cables, further improving signal integrity.
Connector Body Material: The body is likely made of a durable metal like brass or stainless steel.
Contact Plating: Typically, gold or silver plating is used on the connector contacts to ensure low contact resistance and excellent conductivity.
Center Conductor: The center conductor is likely made of copper or beryllium copper for high conductivity.
Insulator Material: The insulator material is usually PTFE (Teflon) for its excellent electrical properties and high temperature resistance.
