Description
SMA Jack (Female) to SMA Reverse-Polarity Jack (Female) | Straight Adapter | Screw-Lock | Stainless Steel Body
The ROSNOL AD-A2A75A/9X-9X is a robust straight adapter for 50 Ω systems operating from DC to 18 GHz. It offers VSWR ≤ 1.20 (return loss ≥ 20.83 dB), insertion loss ≤ 0.05 × √f (GHz) dB, and insulation resistance ≥ 5 GΩ. Electrical ratings include test voltage of 1000 V rms, working voltage of 480 V rms, and power handling up to 200 W at 2 GHz. RF leakage is ≥ 100 dB up to 1 GHz. The screw-lock coupling mechanism ensures secure engagement with ≥ 500 mating cycles, axial captivation ≥ 27 N, and recommended torque between 0.8 and 1.1 Nm.
Materials and plating: center contacts are beryllium copper with gold plating (3 µinch) over a non-magnetic nickel-phosphorus underplate (80 µinch). The body is stainless steel with passivation for corrosion resistance, while the insulator is PTFE for excellent dielectric stability. Operating temperature range is −65°C to +155°C.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across 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. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
