The 18 GHz max frequency is the upper -3 dB point for this SMA jack — it means the connector maintains a 50 Ohm transmission line through the launch, so the signal sees no impedance bump that would cause reflections or insertion loss roll-off below that frequency. For sub-6 GHz work (cellular, Wi-Fi, GNSS) the margin is generous; for Ku-band satellite links or 5G mmWave test setups at 18 GHz, the connector is at its rated ceiling, so the PCB launch and cable assembly must match the 50 Ohm impedance to within a few percent. The 500 mating cycles are delivered by the gold-on-beryllium-copper centre contact — beryllium copper retains its spring force after repeated mates, and the gold plating prevents oxidation that would increase contact resistance. That cycle life suits production test fixtures and field-swappable antenna connections; for a permanent-install crimp-on cable assembly the cycle count is secondary to the environmental seal. ## Panel Mount and Termination — What the Flange and Solder Tab Require The shield termination is solder tab, meaning the outer conductor of the cable or the PCB ground plane connects via a solder lug on the flange, not through the threads. That gives a lower-inductance ground return than a solder-cup shield termination, which matters for keeping the shield current path short at microwave frequencies. The contact termination is also solder tab — a flat lug that solders directly to a pad or wire, not a cup that wraps around the conductor. For a PCB launch, the centre pin height above the board surface must match the trace stack-up to keep the impedance through the transition; the flange provides a reference plane for the ground vias. ## How the 901-2PB100000AE Compares to the 901-2PF100000AE The 901-2PF100000AE is the closest functional sibling in the 901-2P base series — same SMA jack, female socket, 50 Ohm impedance, 18 GHz max frequency, stainless steel body, flange mount, and 500 mating cycles. The difference is the contact termination: the 901-2PB100000AE uses a solder tab, while the 901-2PF100000AE uses a solder cup. For a PCB launch where you want a flat pad connection, the solder tab is the cleaner fit; for a cable assembly where you wrap the conductor into a cup, the solder cup version is the one. The rest of the RF performance is identical — the choice is purely about termination style, not signal integrity.","metaTitle":"Amphenol RF 901-2PB100000AE SMA Jack, 50 Ohm, 18 GHz","metaDescription":"Amphenol RF 901-2PB100000AE SMA jack, female socket, 50 Ohm impedance, 18 GHz max frequency.","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":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"-","Cable Group":"-","Body Material":"Stainless Steel","Housing Color":"-","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Jack, 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":"Flange","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"901-2P","Contact Termination":"Solder Tab","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":"$9.7300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b2ee2a8cbf2ccab5515756b9ec7ebc64.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/901-2PB100000AE/alternatives.json"},"ai":{"faq":[{"question":"Is 901-2PB100000AE available via RFQ confirmation?","answer":"Stock levels and lead time are confirmed at quote time through our independent distribution channel — no on-shelf guarantee is carried on this listing."},{"question":"What is the mating cycle life of 901-2PB100000AE?","answer":"The gold-plated beryllium copper centre contact and stainless steel body maintain repeatable RF performance and low contact resistance across that cycle count, making it suitable for production test fixtures and field-swappable antenna connections."},{"question":"What is the impedance of 901-2PB100000AE?","answer":"The 901-2PB100000AE is a 50 Ohm SMA jack.
