SMA Jack (Female) to HN Jack (Female) RF Adapter | Screw-On | Brass Body
The ROSNOL AD-A2HN25A/94-94 is a high-quality 50Ω RF adapter engineered to connect SMA Jack (Female) and HN Jack (Female) interfaces. Supporting frequencies from DC to 4 GHz, this straight adapter offers VSWR ≤ 1.25, insertion loss ≤ 0.06 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and a 500 V rms voltage rating. These characteristics help ensure efficient signal transmission and low reflection in RF and microwave systems.
The SMA and HN center contacts are manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating for superior conductivity, excellent wear resistance, and long mating life. The brass bodies are finished with copper-tin-zinc alloy plating to improve corrosion resistance, while PTFE insulators provide stable dielectric performance under demanding operating conditions.
This adapter is widely used in wireless communications, RF distribution systems, antenna installations, broadcast infrastructure, test and measurement equipment, and industrial networking applications. Its compact design, reliable RF performance, and durable construction make it an excellent choice for professional RF interconnection requirements.
