SMA Plug (Male) to N Jack (Female) Adapter, DC-12GHz VSWR 1.15

SMA Plug (Male) to N Jack (Female) RF Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1N25A/911-94 adapter provides secure RF connectivity between SMA plug (male) and N jack (female) interfaces. It supports 50 Ω impedance and operates from DC to 12 GHz with VSWR ≤ 1.15 (≥23.13 dB return loss). Electrical performance includes insertion loss ≤ 0.05 × √F(GHz) dB, insulation resistance ≥ 5 GΩ, and test voltage up to 1000 V rms. Rated for 480 V rms working voltage, it handles up to 200 W at 2 GHz and ensures RF leakage ≥100 dB up to 1 GHz.  

The SMA side features beryllium copper contacts with gold plating over non-magnetic nickel-phosphorus underplating, brass body with gold plating, PTFE insulation, silicone rubber gasket, and brass coupling nut. The N side uses beryllium copper contacts, brass body with copper-tin-zinc alloy plating, and PTFE insulation. Mechanical integrity includes screw-lock coupling, ≥500 mating cycles, axial captivation ≥27 N (SMA) and ≥28 N (N), and coupling torque of 1.70 Nm. Operating temperature range is -5°C to +165°C, compliant with MIL-STD-202 standards for thermal shock, vibration, corrosion, and moisture resistance.
