Description
BNC Jack (Female) to SSMB Jack (Female) Adapter | Bayonet-lock & Snap-On | Brass Body
The AD-B2SB25A/94-91 is a precision-engineered straight adaptor designed to facilitate a seamless interface between BNC female and SSMB female connections. Engineered for high-reliability RF and microwave interconnect applications, this adaptor supports a wide frequency range from DC to 4 GHz. It maintains exceptional signal integrity with a VSWR of and a return loss . The electrical performance is further characterized by low insertion loss, calculated at (GHz) dB, and a nominal impedance of 50 . To ensure stable connectivity, the unit features a center contact resistance of on the BNC side and on the SSMB side, coupled with robust outer contact resistances.
Constructed with premium materials, this adaptor utilizes Beryllium Copper for the center contacts and high-grade Brass for the body components to ensure mechanical longevity and superior conductivity. The center contacts are finished with a high-quality 3-micro-inch gold plating over a non-magnetic nickel-phosphorus underplating to minimize intermodulation and maximize corrosion resistance. PTFE insulators are integrated to provide excellent dielectric properties across a broad temperature range from -65°C to +165°C. This rugged design makes the adaptor ideal for demanding environments requiring thermal shock resistance and moisture protection, serving critical roles in telecommunications, aerospace, and laboratory testing setups.
