The brass body carries a gold finish, and the beryllium copper centre contact is gold-plated — a combination that delivers consistent RF performance across the band and resists corrosion in field-service environments. ## Frequency and Signal Integrity Rated to 27 GHz maximum frequency, this jack covers the full Ku-band and well into K-band, making it suitable for microwave test points, antenna feeds, and high-speed digital backplanes where the signal path must stay within a 50 Ohm environment. The solder shield termination — rather than a crimp or clamp — gives a low-inductance ground return at the cable braid, which is critical for maintaining consistent impedance through the transition from cable to connector. This jack is built for RG-405 (.086 inch semi-rigid) cable — the same family used in phase-stable assemblies for test equipment and microwave modules. For a threaded SMA, 500 cycles is a standard endurance figure — sufficient for production test racks and field-swappable modules, though a lab environment with daily reconnections will eventually reach end-of-life on the threads before the contacts degrade.","metaTitle":"TE Connectivity 2081885-1 SMA Jack, 27 GHz, 50 Ohm, RG-405","metaDescription":"TE Connectivity 2081885-1 SMA jack, female socket, 50 Ohm, 27 GHz max, RG-405 semi-rigid cable, gold body, 500 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bag","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"RG-405 (.086 Semi Rigid)","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"335 V","Connector Style":"SMA","Frequency - Max":"27 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"2081885","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.4500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/0b0b2a76b6ec14f26890101a5e6ee44b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 2081885-1 compatible with RG-405 cable?","answer":"Yes, the 2081885-1 is designed for RG-405 (.086 inch semi-rigid) cable, with both the centre contact and shield terminated by solder."},{"question":"Is 2081885-1 a male or female connector?","answer":"The 2081885-1 is a jack, female socket — it accepts a male pin (plug) and mates with a threaded SMA plug."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2081885-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/2081885-1 when reusing this data.
