It's built for test equipment, RF modules, and instrumentation where a panel-mount or board-edge SMA launch needs repeatable performance. ## What 18 GHz and 500 Cycles Mean on the Bench The 18 GHz max frequency means this connector passes signals cleanly through the full microwave S, C, X, and Ku bands — useful for radar, satellite links, and high-speed digital clocks. The 500 mating cycles rating tells you the gold-on-beryllium copper contact will hold its contact resistance through repeated connect/disconnect cycles in a test rack or field-deployed system. ## Mating and Termination — What Connects Here This is an SMA receptacle — it mates with any standard SMA male plug (pin contact) with the same 1/4-36 UNEF threaded coupling. Through-hole mounting means the body legs go into the PCB and get soldered, giving a solid ground plane connection.","metaTitle":"TE Greenpar SMA Receptacle 1-1478979-0, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity Greenpar SMA receptacle, female socket, 50 Ohm impedance, 18 GHz max frequency, 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":"Greenpar","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Stainless Steel","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole","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":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"1478979","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.9400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1-1478979-0 and get a price?","answer":"Submit a request with your target quantity and we'll confirm availability and current pricing at quote time."},{"question":"What is the mating connector for 1-1478979-0?","answer":"This SMA receptacle mates with any standard SMA male plug (male pin, threaded 1/4-36 UNEF coupling).
