The Hirose BNC-UPA(40) is a BNC-series U-Shape adapter that connects two BNC plugs with male center pins — a same-series in-line coupler for extending or joining coaxial cable runs. The body is brass with a silver finish, the center contact is beryllium copper with silver plating, and the dielectric is PTFE. It is a free-hanging (in-line) adapter with bayonet locks on both ends. ## Key RF Specifications and What They Mean The 50 Ohm impedance matches standard RF test and telecom systems. The 4 GHz frequency ceiling is a hard limit. ## Lifecycle and Sourcing — Last Buy Status The BNC-UPA(40) is on Last Buy status. That means the manufacturer has ceased regular production and this is the final procurement window. There is no official replacement order code on record from Hirose for this adapter. If you need a long-term supply, consider qualifying a functionally equivalent BNC male-to-male adapter from another manufacturer while stock remains.","metaTitle":"BNC-UPA(40) BNC Plug to Plug Adapter, 50 Ohm, 4 GHz","metaDescription":"BNC-UPA(40) BNC male-to-male adapter, 50 Ohm impedance, 4 GHz max, silver-plated contacts, 1000 mating cycles.
