N Plug (Male) to TNC Jack (Female) Adapter, DC-10GHz VSWR 1.20

N Plug (Male) to TNC Jack (Female) | Straight Adapter | Screw-Lock | Brass Body

The ROSNOL AD-N1T25A/144-94 is a straight RF adapter designed for secure connectivity between N plug male and TNC jack female interfaces. It operates from DC to 10 GHz with 50-ohm impedance, VSWR ≤ 1.20, and insertion loss ≤ 0.05√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, working voltage 500 V rms, and power handling up to 80 W at 2 GHz under VSWR 1.0. The adapter features screw-lock coupling on both sides, axial captivation ≥ 28 N, and supports at least 500 mating cycles. Recommended torque is 0.7–1.1 Nm for the N side and 0.46–0.69 Nm for the TNC side.

Material construction ensures durability and signal integrity. The TNC center contact is beryllium copper with gold plating 3 microinch over a non-magnetic nickel-phosphorus underplating 80 microinch; its body is brass with copper-tin-zinc alloy finish and PTFE insulator. The N side uses a brass center contact with gold plating over nickel-phosphorus, a brass body finished with copper-tin-zinc alloy, and a silicone rubber gasket for sealing. Coupling nuts are brass with copper-tin-zinc alloy finish.
