Experience low VSWR (1.15+0.02F for flexible cable, 1.10+0.02F for semi-rigid) and unmatched performance.

Key Features of the SMA-KFD329 HUADA Coaxial Connector

Frequency Range:
The SMA-KFD3 operates across an impressive frequency range, spanning from DC (direct current) up to 18 GHz. Whether you’re dealing with low-frequency signals or high-frequency applications, this connector has you covered.

Insertion Loss:
The insertion loss is a critical parameter that affects signal quality. For the SMA-KFD3, the insertion loss follows a formula: Insertion Loss=0.1×fGHz
dB. As the frequency increases, the insertion loss gradually rises, but it remains within acceptable limits for most applications.

VSWR (Voltage Standing Wave Ratio) / Return Loss:
VSWR measures how efficiently a connector transfers energy between the source and load. The SMA-KFD3 maintains excellent VSWR performance across its entire frequency range (1.25 to 18 GHz). Low VSWR ensures minimal signal reflection and maximum power transfer.
Additionally, the return loss (a complementary metric) quantifies how much signal power is reflected back. The SMA-KFD3’s design minimizes return loss, contributing to reliable signal integrity.

Materials:
Center Contact: The center contact is made of gold-plated Beryllium Copper, ensuring good conductivity and corrosion resistance.
Outer Contact and Body: Both the outer contact and body are constructed from gold-plated brass, providing durability and stable performance.
Dielectric Material: The dielectric material is PTFE (polytetrafluoroethylene), known for its low loss and high dielectric strength.
Operating Temperature Range:
The SMA-KFD3 can handle extreme environments. It operates reliably from -40°C to +165°C, making it suitable for various industrial, aerospace, and communication applications.
