SMA Jack (Female) to QMA Jack (Female) Bulkhead Adapter Epoxy Captivated, DC-18GHz, VSWR 1.20

SMA Jack (Female) to QMA Jack (Female) Adapter | Bulkhead | Screw-Lock & Quick-Lock | Epoxy Captivation | Brass Body

The ROSNOL AD-A2QA25A-BH-EC/94-94 is a high-performance RF adapter designed for sealed bulkhead installations in demanding environments. Operating from DC to 18 GHz with a 50-ohm impedance, it achieves VSWR ≤ 1.20 and insertion loss ≤ 0.05√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, test voltage 1000 V rms, and RF leakage ≥ 90 dB up to 1 GHz. Mechanical integrity is guaranteed through screw-lock coupling on the SMA side and quick-lock engagement on the QMA side, with axial contact captivation ≥ 20 N and ≥ 500 mating cycles for secure and repeatable connections.

Engineered with brass bodies for enhanced durability, the adapter incorporates beryllium copper contacts plated with gold over nickel-phosphorus underplating. PTFE insulators, silicone rubber gaskets, and epoxy captivation provide superior sealing and mechanical strength for long-term reliability across a temperature range of -40°C to +85°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.
