Description
BNC Plug (Male) to BNC Jack (Female) | Straight Adapter | Bayonet-Lock | Brass Body
The ROSNOL AD-B1B25A/H33-H3 is a straight RF adapter designed for 50-ohm applications, covering DC to 6 GHz with VSWR ≤ 1.30 (return loss ≥ 17.7 dB). It specifies 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 interface ensures ≥ 500 mating cycles and center contact captivation ≥ 15 N.Constructed with brass bodies and coupling nuts plated with nickel, this adapter includes phosphor bronze center contacts plated with 3 micro-inch gold over 80 micro-inch non-magnetic nickel-phosphorus underplating, PTFE insulators, and silicone rubber gaskets for superior corrosion resistance and mechanical stability.
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.
