Key Features of the HUADA SMA-JFD91 Connector

Impedance: The SMA-JFD91 connector has an impedance of 50Ω. This value is crucial for matching the impedance of the connector to the transmission line or cable it connects to. Proper impedance matching ensures efficient signal transfer and minimizes reflections.
Operating Temperature Range: The SMA-JFD91 can withstand extreme temperatures:
Minimum Operating Temperature: -65°C
Maximum Operating Temperature: +165°C
This wide temperature range makes it suitable for various environments, including aerospace, industrial, and telecommunications applications.
Mating Cycles: The connector is rated for 500 mating cycles. This means it can be connected and disconnected up to 500 times without compromising its performance. Frequent mating cycles are common in testing, maintenance, and production scenarios.
Insulation Resistance: The SMA-JFD91 exhibits an insulation resistance of 5000 MΩ. High insulation resistance ensures that the connector maintains electrical isolation between its conductive parts, preventing leakage or short circuits.
Dielectric Withstanding Voltage: The connector can withstand a dielectric voltage of up to 1000 V. This property is essential for safety and reliability, especially in high-voltage applications.
Frequency Range: With flexible cables, the SMA-JFD91 operates within the frequency range of 0~12.4GHz.
For semi-rigid cables, it extends up to 0~18GHz.
These wide frequency bands cover various communication systems, including 5G, satellite, and microwave applications.
Voltage Standing Wave Ratio (VSWR): VSWR measures how efficiently a connector transfers power from the source to the load. Lower VSWR values indicate better performance.
For flexible cables, the SMA-JFD91 has a VSWR of 1.15 + 0.02F, where F represents the frequency in GHz.
For semi-rigid cables, the VSWR is 1.10 + 0.02F.
These low VSWR values ensure minimal signal loss and optimal system performance.
