The gold-plated brass body and beryllium copper center contact with gold plating keep the insertion loss low across the full millimeter-wave band. ## What the 40 GHz Rating Means for the Signal Path The 40 GHz maximum frequency sets the usable bandwidth for this SMPM receptacle — it covers the entire Ku, K, and Ka bands, plus the lower end of the millimeter-wave spectrum. At 40 GHz, the 50 Ohm impedance tolerance and the PTFE dielectric control the phase stability through the launch. The 175 V voltage rating is a dielectric-withstand ceiling, not a continuous operating limit; at these frequencies the signal voltage is a fraction of that. The 100 mating cycles are typical for a blind-mate connector in a backplane or module interface — the snap-on coupling wears the detent over time, so this isn't a test-port connector for daily connect/disconnect. ## Cable and Termination — RG-405 Only, Solder Both Ends This receptacle is designed for RG-405 (.086\" semi-rigid) coax — the cable group is specified in the part number and the center contact bore, shield diameter, and dielectric support are sized for that cable. ## Comparing the 2406866-1 to the 1057230-1 OSP Peer Both use snap-on coupling, solder termination, and gold-plated beryllium copper center contacts, and both are rated for RG-405 (.085\" semi-rigid) cable. The critical difference is bandwidth: the 2406866-1 SMPM receptacle is rated to 40 GHz, while the 1057230-1 OSP jack stops at 22 GHz. If your signal path stays below 22 GHz, the 1057230-1 is a viable alternative with a stainless body that resists corrosion better than brass. Above 22 GHz, the 2406866-1 is the only choice between these two.","metaTitle":"TE Connectivity 2406866-1 SMPM Receptacle, 40 GHz, RG-405","metaDescription":"TE 2406866-1 SMPM blind-mate receptacle, female socket, 50 Ohm, DC to 40 GHz.","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":"RG-405 (.086 Semi Rigid)","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line), Right Angle","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":"2406866","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~125°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$31.2900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/efc90c31808d1b1504bca6b94ff75784.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the TE 2406866-1 SMPM receptacle?","answer":"No stock-holding or immediate-shipment claim is made on this page."},{"question":"What cable is compatible with the 2406866-1?","answer":"The 2406866-1 is designed for RG-405 (.086\" semi-rigid) coax cable.
