FAQS
-
How does the 2-hole flange improve RF stability?
- The 2-hole flange mount provides rigid mechanical support, minimizing vibration-induced signal disruptions and ensuring a secure ground connection for stable RF performance.
-
What impact does PTFE insulation have on signal integrity?
- PTFE (Polytetrafluoroethylene) offers low dielectric loss and high thermal stability, reducing insertion loss and maintaining consistent impedance matching across high frequencies.
-
Why is gold-plating essential for SMA connectors?
- Gold-plated contacts reduce oxidation and contact resistance, ensuring low-loss signal transmission, enhanced RF conductivity, and long-term durability in high-frequency applications.
-
What is the recommended torque for mating this SMA connector?
- To prevent thread damage and impedance mismatch, the SMA Female connector should be tightened to 0.6–1.1 Nm (5–10 in-lbs) using a calibrated torque wrench.
-
How does VSWR affect the performance of this connector?
- A low VSWR (≤1.3 up to 3 GHz, ≤1.5 up to 6 GHz) minimizes signal reflection, maximizing power transfer efficiency and ensuring consistent RF performance across the operating range.
