Description
SMA Jack (Female) to Precision N Jack (Female) Adapter | Straight Design | Screw-Lock | Brass & Stainless Steel Body
The ROSNOL AD-A2PCN25B/91-9X is engineered for high-frequency applications requiring robust and precise connectivity. With a 50-ohm impedance and DC to 18 GHz frequency range, it delivers VSWR ≤ 1.15 and insertion loss ≤ 0.1√F (GHz) dB. Electrical specifications include insulation resistance ≥ 5 GΩ, test voltage 1000 V rms, and RF leakage ≥ 90 dB up to 1 GHz. Mechanical reliability is guaranteed through screw-lock coupling, axial contact captivation ≥ 28 N, and ≥ 500 mating cycles, ensuring secure and repeatable connections.Material construction features beryllium copper contacts plated with gold over nickel-phosphorus underplating, brass body with gold finish on the SMA side, and stainless steel body with passivated finish on the Precision N side. PTFE insulators provide excellent dielectric properties for consistent signal integrity across a temperature range of -65°C to +165°C.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide 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 fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
