Discover the HUADA SMA-KY3 RF Coaxial Connector: Precision Engineering for Reliable Connections

The SMA-KY3 connector is designed with precision and performance in mind. Its 50Ω impedance ensures efficient signal transmission across a broad frequency range from DC to 18 GHz. Whether you’re building communication networks, radar systems, or test setups, this connector delivers consistent results. Its robust construction withstands extreme temperatures, from -65°C to +165°C, making it suitable for demanding environments. Additionally, the SMA-KY3 can endure 500 mating cycles, ensuring longevity and reliability.
When it comes to signal integrity, the SMA-KY3 shines. Its low VSWR (Voltage Standing Wave Ratio) of ≤1.05 + 0.1f (GHz) minimizes reflections, crucial for maintaining clean signals. Whether you’re connecting antennas, amplifiers, or RF modules, this connector ensures minimal loss. The dielectric withstanding voltage of 1000 V adds an extra layer of safety. From flexible cable applications (0~12.4 GHz) to semi-rigid setups (0~18 GHz), the SMA-KY3 adapts seamlessly.

Key Features of the SMA-KY3 HUADA Coaxial Connector

Impedance (Z): The SMA-KY3 operates at 50Ω impedance, ensuring efficient signal transmission and compatibility with standard RF systems.
Frequency Range:
With flexible cables, it covers frequencies from DC up to 12.4 GHz. This versatility makes it suitable for various applications, including wireless communication and instrumentation.
For semi-rigid cables, the range extends up to 18 GHz, catering to high-frequency needs.
Voltage Rating: The connector can handle up to 500 V(rms), providing safety and reliability in demanding environments.
Operating Temperature Range: From a chilly -65°C to a scorching +165°C, the SMA-KY3 remains robust and functional. Whether in Arctic conditions or near industrial machinery, it won’t let you down.
VSWR (Voltage Standing Wave Ratio):
VSWR measures how efficiently the connector transfers energy. The SMA-KY3 achieves a maximum VSWR of 1.10 + 0.025×f(GHz). Lower VSWR means less signal loss and better performance.
Translation: Your signals stay clean, even at high frequencies.
Contact Resistance: Center Conductor: ≤3 mΩ, Outer Conductor: ≤2 mΩ. These low resistance values ensure minimal signal loss and reliable connections.
Insulation Resistance: With an insulation resistance of ≥5000MΩ, the SMA-KY3 maintains signal integrity even in challenging conditions.
Durability: It can withstand 500 mating cycles. So, whether you’re plugging and unplugging frequently or leaving it connected for extended periods, it’s up to the task.
Material Composition:
Center Contact: Beryllium copper (Gold plated over Nickel) – Ensures good conductivity.
Body, Coupling Nut: Brass (Gold plated over Nickel) – Sturdy and corrosion-resistant.
Insulator: PTFE (Polytetrafluoroethylene) – Provides electrical isolation and thermal stability.
Weight: A mere 4.2 grams. Lightweight but heavy on performance!
