SMA Jak (Female) to SMB Jack (Female) Adapter, DC-4GHz VSWR1.35

SMA Jack (Female) to SMB Jack (Female) Adapter | Screw-Lock | Brass Body

The ROSNOL AD-A2S25A/91-91 is a precision RF adapter designed for low-frequency applications requiring reliable connectivity. Operating from DC to 4 GHz with a 50-ohm impedance, it achieves VSWR ≤ 1.35 and insertion loss ≤ 0.04√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, test voltage 750 V rms, and RF leakage ≥ 55 dB up to 1 GHz. Mechanical integrity is ensured through screw-lock coupling on both ends, axial contact captivation ≥ 10 N, and ≥ 500 mating cycles, supporting contact current up to 1.5 A DC.

Constructed with brass bodies for durability, the adapter incorporates beryllium copper contacts plated with gold over nickel-phosphorus underplating. PTFE insulators provide excellent dielectric properties, ensuring stable performance 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.
