Description
SMA RP Jack (Female) to BNC Jack (Female) Adapter | Straight Design | Screw-Lock & Bayonet-Lock | Brass Body
The ROSNOL AD-A7B25A/91-94 adapter provides secure connectivity between SMA reverse-polarity and BNC connectors for RF systems. Operating from DC to 6 GHz with 50 Ω impedance, it achieves VSWR ≤1.15 up to 4 GHz and ≤1.2 up to 6 GHz. Insertion loss remains below 0.05 × √F (GHz) dB, with insulation resistance ≥5 GΩ and RF leakage ≤80 W at 2 GHz. Rated for 1000 V RMS test voltage and 400 V RMS working voltage, this adapter supports ≥500 mating cycles with screw-lock on the SMA side and bayonet-lock on the BNC side.The center contacts are beryllium copper with gold plating over nickel-phosphorus underplating for superior conductivity. Brass bodies feature protective plating, complemented by PTFE insulators for excellent dielectric strength. The adapter withstands temperatures from -65°C to +165°C, ensuring durability in demanding environments.
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.
