This is a bulkhead-front-side-nut receptacle: the connector body passes through a panel hole, and the nut and lockwasher clamp it from the front. The shield braid is soldered to the body, and the centre conductor is soldered into a cup — no crimp tool needed, but the solder joint must be clean to avoid cold joints that shift the impedance at 18 GHz. The 500 mating cycles rating means the gold-over-beryllium copper contact can handle repeated test-port or antenna swaps without the centre pin losing its spring force.","metaTitle":"Amphenol RF 901-9890-RFX SMA Receptacle, 50 Ohm, 18 GHz","metaDescription":"Amphenol RF 901-9890-RFX SMA panel-mount receptacle, 50 Ohm, 18 GHz, gold-plated beryllium copper contact, solder cup termination, 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":"Amphenol RF","Series":"-","Package":"Bulk","Features":"Extended Insulation","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"901-98","Contact Termination":"Solder Cup","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":"$9.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/34491416c46135ecc3e85b9edfaa8ba9.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/901-9890-RFX/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 901-9890-RFX?","answer":"The 901-9890-RFX is a 50 Ohm SMA receptacle, rated to 18 GHz maximum frequency."},{"question":"What connectors mate with 901-9890-RFX?","answer":"The 901-9890-RFX is an SMA female socket receptacle.
