HUADA SMA-KFD175: High Performance RF Coaxial Connector for Demanding Applications

The HUADA SMA-KFD175 RF coaxial connector is a high-performance, reliable solution for 50Ω applications. Designed for demanding environments, this connector boasts exceptional durability and wide operating temperature range, making it ideal for various RF systems. Featuring a robust construction, it delivers excellent electrical performance with a frequency range extending from 0 to 18 GHz for semi-rigid cables and 0 to 12.4 GHz for flexible cables. Its low VSWR (1.15+0.02F for flexible cables and 1.10+0.02F for semi-rigid cables) ensures minimal signal loss, crucial for maintaining signal integrity in sensitive applications.
The SMA-KFD175 is engineered for demanding environments with a wide operating temperature range of -65°C to +165°C. This connector's 500 mating cycles guarantee consistent performance and reliability even under frequent connection and disconnection. Its 5000 MΩ insulation resistance and 1000V dielectric withstanding voltage ensure optimal signal isolation and protection against high voltage conditions.

Key Features of the SMA-KFD175 HUADA Coaxial Connector

Connector Type: SMA (Subminiature A)
Impedance: 50Ω (standard for RF applications)
Frequency Range: This is where it gets more specific. You mentioned two frequency ranges: With Flexible Cable: 0~12.4GHz , With Semi-Rigid Cable: 0~18GHz
Important Note: The frequency range of the connector itself is usually much higher than this, but the actual usable frequency range is limited by the type of cable used. Flexible cables have higher losses at higher frequencies, hence the lower limit.
Operating Temperature: -65°C to +165°C. This wide range indicates suitability for demanding environments and a high degree of reliability.
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. A high value indicates good electrical isolation and prevents signal leakage.
Dielectric Withstanding Voltage: 1000V. This measures the connector's ability to withstand high voltage without breaking down.
VSWR (Voltage Standing Wave Ratio): With Flexible Cable: 1.15+0.02F, With Semi-Rigid Cable: 1.10+0.02F. A lower VSWR is desirable as it indicates less signal reflection and higher signal efficiency.
Connector Body Material: The body is likely made of a durable metal like brass or stainless steel.
Contact Plating: Usually, gold or silver plating is used to ensure low contact resistance and excellent conductivity.
Center Conductor: The center conductor material is typically copper or beryllium copper.
Insulator Material: The insulator is often made of PTFE (Teflon) for its excellent electrical properties and high temperature resistance.
