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

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

The ROSNOL AD-A1N25A/933-93 is a precision RF adapter engineered to provide stable signal performance from DC to 12 GHz. Designed with a 50-ohm impedance and a maximum VSWR of 1.15, it ensures low reflection and consistent return-loss characteristics for measurement systems, communication equipment, RF modules, and laboratory instrumentation. The adapter supports insulation resistance of ≥ 5 GΩ, offers a 1000 Vrms test voltage rating, and maintains RF leakage levels of ≥ 100 dB up to 1 GHz. Power handling capability reaches 200 W at 2 GHz, making it suitable for mid‑power transmission paths and general-purpose RF interconnect applications.

Constructed with durability and electrical stability in mind, the AD-A1N25A/933-93 features gold-plated beryllium-copper center contacts with non-magnetic nickel-phosphorus underplating, nickel-plated brass bodies, and PTFE dielectric insulation on both SMA and N sides. The screw-lock coupling mechanism supports a minimum of 500 mating cycles, reinforced by axial captivation ≥ 28 N and robust coupling-nut retention ratings (≥ 270 N on SMA, ≥ 450 N on N). Recommended torque values—0.57 Nm for SMA and 1.0 Nm for N—ensure repeatable, secure mechanical engagement across varying operating conditions. The adapter performs reliably within a temperature range of −65°C to +165°C.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across a broad range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
