Description
Mini UHF Plug (Male) to BNC Jack (Female) | Straight Design | Screw-Lock & Bayonet-Lock | Brass Body
The ROSNOL AD-MU1B25A/933-93 is engineered for RF systems requiring stable performance up to 2.5 GHz with 50 ohm impedance. It delivers low insertion loss and excellent return loss for optimal signal integrity. Electrical ratings include center contact resistance ≤5 mΩ on the Mini UHF side and ≤1.5 mΩ on the BNC side, outer contact resistance ≤5 mΩ and ≤1 mΩ respectively, and test voltage up to 1500 Vrms. Power handling is rated at 400 W at 300 MHz under VSWR 1.0 conditions. Screw-lock coupling on the Mini UHF side and bayonet-lock on the BNC side ensure secure engagement, with mechanical durability exceeding 500 mating cycles.Materials and plating are optimized for conductivity and durability. Both sides feature beryllium copper center contacts with gold plating over nickel-phosphorus underplating, brass bodies nickel plated, and PTFE insulators for dielectric stability. Coupling nuts are brass nickel plated for corrosion resistance. The adapter operates within a temperature range of −55°C to +145°C.
ROSNOL’s RF adapters deliver consistent quality and cost efficiency, making them a reliable alternative to leading European and American brands. All ROSNOL 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 meet specialized interconnect requirements.
