Description
BNC Jack (Female) to BNC Jack (Female) | Straight Adapter | Bayonet-Lock | Stainless Steel Body
The ROSNOL AD-B2B25A/9X-9X is a straight RF adapter for 50-ohm systems, operating from DC to 4 GHz with VSWR ≤ 1.20 (return loss ≥ 20.83 dB). It offers insertion loss ≤ 0.05 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 1.5 mΩ, and outer contact resistance ≤ 1 mΩ. Electrical ratings include 1500 V rms test voltage, 400 V rms working voltage, and power handling up to 80 W at 2 GHz. The bayonet-lock coupling ensures secure engagement with ≥ 500 mating cycles and center contact captivation ≥ 15 N.This adapter features stainless steel bodies and coupling nuts with passivated finish, beryllium copper center contacts plated with 3 micro-inch gold over 80 micro-inch non-magnetic nickel-phosphorus underplating, PTFE insulators, and silicone rubber gaskets for enhanced durability and corrosion resistance.
ROSNOL’s precision-engineered RF adapters deliver reliable performance at competitive pricing, making them a strong 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.
