RF Cable Quality & Specification Guidelines
Electrical
-
Impedance: 50 Ω ±2 Ω
-
Frequency Range: DC – 3 GHz (guaranteed)
-
VSWR: ≤ 1.5:1 across rated band
-
Insertion Loss: Length-appropriate, within LMR-240 reference values
-
Shielding: Double-shielded coax (braid + foil or equivalent)
Each RP3 TECH Labs cable is electrically verified prior to shipment.
Connector Quality Standards (Critical for RF)
Connector Materials
-
Gold-plated center pins (SMA, N)
-
Nickel-plated bodies (BNC, TNC)
-
Precision-machined dielectric supports
Termination Quality
Termination Quality
-
Correct pin protrusion (flush ±0.25 mm)
-
Uniform crimp with correct hex die
-
No braid whiskers near the dielectric
-
No visible gaps between the connector body and the jacket
📌 Tip: Poor connectors cause more RF problems than cable loss.
All cables are assembled, inspected, and electrically verified by RP3 TECH Labs.
