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

The ROSNOL AD-N1SC25A/144-94 is a straight RF adapter designed for secure connectivity between N plug male and SC jack female interfaces. It operates from DC to 11 GHz with 50-ohm impedance and VSWR ≤ 1.25. Electrical performance includes return loss ≥ 19.1 dB, insulation resistance ≥ 1 GΩ, and robust mechanical reliability with screw-lock on the N side and quick-lock on the SC side. The adapter supports at least 500 mating cycles on both ends and withstands temperatures from -65°C to +165°C.

Material construction ensures durability and signal integrity. The SC 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 nut is brass with copper-tin-zinc alloy finish.
