The ROSNOL AD-A2SB25A/91-91 is engineered for low-frequency applications requiring secure and reliable connectivity. With a 50-ohm impedance and DC to 4 GHz frequency range, it delivers VSWR ≤ 1.35 and insertion loss ≤ 0.05√F (GHz) dB. Electrical specifications include insulation resistance ≥ 5 GΩ, test voltage 750 V rms, and RF leakage ≥ 55 dB up to 1 GHz. Mechanical features include screw-lock coupling on both ends, axial contact captivation ≥ 10 N, and ≥ 500 mating cycles, supporting contact current up to 1.5 A DC.Material construction features beryllium copper contacts plated with gold over nickel-phosphorus underplating, brass bodies with gold finish for enhanced corrosion resistance, and PTFE insulators for superior dielectric stability. This design ensures durability 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.
