It carries a 6 GHz frequency ceiling, making it suitable for WiFi (2.4/5 GHz), Bluetooth, GPS, and lower microwave bands. The snap-on fastening type gives a quick, positive mate without threads — the gold-on-gold contact interface (gold body finish, gold center contact plating) supports 500 mating cycles before the specified contact resistance drift. ## Board Layout: SMT Footprint and Ground Pad This is a surface-mount part with the shield termination soldered directly to the PCB ground plane. The center contact and outer shield both terminate via solder — no through-hole posts. For best return loss, keep the trace width and ground clearance on the top layer matched to the 50 Ohm target for the board stack-up. ## Mating and Cable Assembly Fit The 908-22109 mates with any standard MMCX male plug (typically on a semi-rigid or flexible coax cable assembly). The snap-on retention is the defining interface — no coupling nut, just push to mate, pull to release. The female socket accepts the male centre pin; the gold-on-beryllium copper centre contact gives good spring retention over the 500-cycle life. For a cable assembly, pair this jack with an MMCX male plug terminated to RG-178, RG-316, or similar 50 Ohm coax. The single-port configuration means one RF channel per connector.","metaTitle":"Amphenol RF 908-22109 MMCX Jack, 50 Ohm, 6 GHz, SMT","metaDescription":"Amphenol RF 908-22109 MMCX jack, female socket, 50 Ohm impedance, 6 GHz max frequency, 500 mating cycles, SMT with solder shield termination.","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":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Surface Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"MMCX","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"90822","Contact Termination":"Solder","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":"$8.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7b158cadc4b1425a3bb1c6519dda4bcb.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/908-22109/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MMCX and MCX connectors?","answer":"MMCX (Micro-MCX) is a smaller, snap-on version of the MCX interface. The 908-22109 is an MMCX jack; the peer 919-382J-51P is an MCX receptacle. MMCX uses a 1/8-inch hex nut for the outer conductor engagement, while MCX uses a 1/4-inch hex. Both are 50 Ohm, but they are not intermateable — the physical dimensions differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/908-22109","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/908-22109 when reusing this data.
