The shield termination is crimp, and the center contact is solder — a common field-termination method for semi-rigid coax. The 50 Ohm impedance and 18 GHz frequency max mean this jack supports signals up to the Ku-band without significant mismatch loss. The dielectric material is polymethylpentene (PMP), chosen for stable RF performance across the temperature range. The 2081204-9 is officially obsolete. For a current-production alternative, look for a TE SMA jack with the same RG-405 cable group, 50 Ohm impedance, and panel-mount bulkhead feature — the KOAXXA series may have an active variant, but verify the interface dimensions and mating cycle rating against your BOM.","metaTitle":"TE Connectivity 2081204-9 SMA Jack, 50 Ohm, 18 GHz, RG-405","metaDescription":"TE Connectivity 2081204-9 SMA jack, 50 Ohm, 18 GHz max, for RG-405 semi-rigid cable.
