SMA Plug for RG-402 Semi-Rigid — 50 Ohm, 18 GHz
It delivers a 50 Ohm impedance path rated to 18 GHz — the full usable bandwidth of the SMA interface. 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.
