It mates with the corresponding QMA plug using a snap-on fastening mechanism — no torque wrench required, which cuts installation time in field-terminated cable assemblies. The connector is supplied as a kit: one jack body and one gold-plated beryllium copper center contact, both in the same order code. The 50 Ohm impedance and 0.25 dB insertion loss at 6 GHz make this a controlled-impedance interconnect for microwave signal paths — think antenna feeds, test equipment front-ends, or base station RF modules where the snap-on convenience justifies a small loss trade-off versus a torqued SMA. This jack is listed exclusively for RG-402 (.141\" semi-rigid) cable. The center contact solders to the signal conductor; the shield terminates to the brass body with a solder joint at the rear. The brass body carries a gold finish — corrosion resistance for outdoor or repeated-handling environments. The gold-on-gold contact interface (gold body finish, gold center contact plating) keeps contact resistance stable across those cycles. ## Electrical and environmental limits The 6 GHz frequency ceiling means this jack supports L-band through C-band signals; above 6 GHz the insertion loss and VSWR climb beyond the 0.25 dB spec at the rated band edge.","metaTitle":"TE Connectivity 1408348-1 QMA Jack, 50 Ohm, 6 GHz, RG-402","metaDescription":"TE Connectivity 1408348-1 QMA jack, female socket, 50 Ohm impedance, 6 GHz max frequency, 0.25 dB insertion loss.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bulk","Features":"-","Includes":"2 pcs - 1 Connector, 1 Contact","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"RG-402 (.141\\\" Semi Rigid)","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Jack, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"0.25dB","Product Status":"Active","Voltage Rating":"335 V","Connector Style":"QMA","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"1408348","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~80°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.6587","stockQuantity":47,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a50aa7396207ac72fc5403a6519e83e0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does 1408348-1 fit RG-402 cable?","answer":"Yes, the 1408348-1 is listed specifically for RG-402 (.141\" semi-rigid) cable.
