SMA Plug (Male) to TNC Jack (Female) Adapter, DC-11GHz VSWR 1.20

SMA Plug (Male) to TNC Jack (Female) | Straight Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1T25A/H44-H4 adapter ensures robust RF performance with 50 Ω impedance and DC–11 GHz frequency range. It achieves VSWR ≤ 1.20, insertion loss ≤ 0.04 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Rated for 1000 V rms test voltage and 480 V rms working voltage, it guarantees RF leakage ≥ 100 dB up to 1 GHz and power handling up to 80 W at 2 GHz. Mechanical integrity includes screw-lock coupling, axial captivation ≥ 27 N, torque range 0.8–1.1 Nm (SMA) and 0.46–0.69 Nm (TNC), and minimum 500 mating cycles.

The SMA and TNC bodies are brass with copper-tin-zinc alloy for enhanced durability. Center contacts are phosphor bronze with 3 μinch gold plating over 100 μinch non-magnetic nickel-phosphorus underplating. Insulators are PTFE for both ends, complemented by silicone rubber gaskets for environmental sealing. Dimensions include overall length 26.75 mm [1.053 in], hex sizes 8 mm [.315 in] and 12 mm [.472 in], and thread 7/16-28 UNEF-2A.
