The stainless-steel sibling 901-9209-ASF extends to 18 GHz, but at a higher cost and with a different body material. For systems operating below 12.4 GHz — common for cellular, Wi-Fi, GPS, and general-purpose RF — the brass-body 901-9985-RFX is the standard choice. The 901-9986-RFX shares the same 12.4 GHz rating and straight jack-to-jack configuration but adds a bulkhead mounting flange with lockwasher and nut for panel-feed applications. ## Construction and Environmental Range The free-hanging (in-line) style means no panel cutout is required; the adapter simply joins two cable assemblies.","metaTitle":"Amphenol RF 901-9985-RFX SMA to SMA Adapter, 12.4 GHz","metaDescription":"Amphenol RF 901-9985-RFX SMA female-to-female barrel adapter, 50 Ohm, straight, rated to 12.4 GHz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Style":"Straight","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Adapter Type":"Jack to Jack","Body Material":"Brass","Center Gender":"Female to Female","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Adapter Series":"SMA to SMA","Fastening Type":"Threaded, Threaded","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"12.4 GHz","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Base Product Number":"901-99","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"SMA Jack, Female Socket","Convert From (Adapter End)":"SMA Jack, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/029decacaa7df4f038e05701cf8e8b04.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/901-9985-RFX/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 901-9985-RFX?","answer":"The 901-9985-RFX is available to order through independent distribution.
