The ROSNOL AD-B2B25A-PF/H4-H4 is a high-quality BNC adapter designed for RF and microwave systems operating from DC to 4 GHz with a 50 Ω impedance. It delivers VSWR ≤ 1.20, insertion loss ≤ 0.05√F (GHz) dB, and insulation resistance ≥ 5 GΩ, ensuring stable signal transmission. Rated for 1500 V RMS test voltage and power handling up to 80 W at 2 GHz, this adapter guarantees reliable performance. The bayonet-lock coupling mechanism provides secure engagement with ≥ 500 mating cycles, making it ideal for robust RF connections.Constructed with premium materials, the center contact is phosphor bronze with gold plating over nickel-phosphorus underplating for superior conductivity and corrosion resistance. The body and coupling nut are brass with copper-tin-zinc alloy finish, complemented by PTFE insulators for excellent dielectric stability. Designed to withstand temperatures from -65°C to +165°C, this adapter ensures durability in demanding environments.
ROSNOL’s precision-engineered RF connectors offer a cost-effective alternative to leading global brands. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH standards, these products guarantee quality and environmental safety. Customization services for plating, materials, and mechanical design are available to meet specialized requirements.
