This is the miniature blind-mate interface — SMPM — designed for dense RF module interconnects where you need a snap-on mate rather than a threaded coupling. It handles signals up to 40 GHz at 50 Ohm impedance, which puts it in the upper band for this connector class, suited for microwave and millimeter-wave assemblies. Termination is solder-only: the shield terminates by solder, and the center contact terminates by solder as well. This is not a crimp connector — it's built for semi-rigid cable, specifically 0.034\" diameter, so plan for a soldering step in your assembly process. Rated for 100 mating cycles, which is moderate for an RF connector — enough for module integration and occasional rework, but not designed for frequent connect-disconnect cycles like a test port. The snap-on fastening gives a positive tactile lock without the torque control needed for threaded connectors. The key difference is frequency: the 2406839-1 runs to 40 GHz, while the 1057230-1 is rated to 22 GHz. The 1057230-1 also uses a stainless steel body and accepts RG-405 (.085\" semi-rigid) cable, a larger diameter than the 0.034\" cable this SMPM receptacle is built for. If your signal path stays under 22 GHz and you need the larger cable, the 1057230-1 is worth a look; for the higher band, the 2406839-1 is the one. This receptacle is designed for 0.034\" semi-rigid coaxial cable — a common size for microwave module pigtails. The free-hanging, in-line mounting means it's not a board-edge launch; it terminates the cable end and mates with a corresponding SMPM plug on the module or bulkhead. The voltage rating is 175 V, which is typical for RF signal lines rather than power delivery.","metaTitle":"TE Connectivity 2406839-1 SMPM Receptacle, 40 GHz, 50 Ohm","metaDescription":"TE Connectivity 2406839-1 Blind-Mate Coaxial SMPM receptacle, female socket, 50 Ohm impedance, 40 GHz max frequency, 175 V rating, 100 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":"Blind-Mate Coaxial","Package":"Bag","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"0.034\\\" Semi Rigid","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"175 V","Connector Style":"SMPM","Frequency - Max":"40 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"2406839","Contact Termination":"Solder","Dielectric Material":"Polyetheretherketone (PEEK)","Operating Temperature":"-40°C~125°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$34.2200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7f57d40ba52a8105b3442e87dad254f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance of 2406839-1?","answer":"The impedance is 50 Ohm, the standard for RF and microwave signal chains."},{"question":"Is 2406839-1 compatible with RG316 cable?","answer":"No — this receptacle is specified for 0.034\" semi-rigid cable only.
