The gold-plated stainless steel body resists corrosion in lab, test, and field environments, while the threaded coupling nut provides vibration-resistant mating. This connector ships as a kit: one SMA plug, one coupling nut, one gasket, and one ring, so no separate hardware sourcing is needed for a single-ended cable assembly. ## Frequency and Impedance — 18 GHz at 50 Ohm Rated to 18 GHz at 50 Ohm, this plug covers the SMA band edge-to-edge — suitable for microwave test leads, antenna feeds, and instrumentation interconnects up through Ku-band. The PTFE dielectric maintains consistent phase and insertion loss across the range. ## Cable Fit and Termination — RG-402 Semi-Rigid This plug is dimensioned for RG-402 (.141\" diameter) semi-rigid cable. The shield termination is solder-type — a standard bench operation with a soldering iron and flux. The 500-cycle mating life is generous for a semi-rigid connector; the gold-plated contact and stainless body resist wear across repeated connect-disconnect cycles in test setups. ## Lifecycle and Sourcing — Obsolete, Sourced to Order No official replacement order code is listed. If you are qualifying a new design, evaluate the current SMA connector family from TE for a form-fit-function alternative.","metaTitle":"TE Connectivity 1050756-1 SMA Plug, 50 Ohm, 18 GHz, RG-402","metaDescription":"TE Connectivity SMA plug, 50 Ohm, 18 GHz max, for RG-402 semi-rigid cable.
