At 40 GHz, the SMP interface maintains a controlled impedance through the blind-mate interface, which means this adapter can sit in a signal chain carrying Ku-band, K-band, or Ka-band signals without introducing a standing-wave mismatch. ## Mating Cycles and Build — What the 100-Cycle Rating Means Rated for 100 mating cycles, this adapter is built for bench-top test, prototype bring-up, and periodic reconfiguration — not for a production harness that sees daily connect-disconnect. The snap-on, snap-on fastening type gives a positive tactile lock when mated, but the beryllium copper spring fingers in the SMP interface wear with each cycle. For a test-jig application where the adapter is mated a few dozen times over its life, the 100-cycle rating provides comfortable margin. For a high-throughput production test socket, look at a higher-cycle SMP variant. ## Compatibility and Mating — What Connects to SMP-FS2A-1674 As an SMP to SMP adapter with female center contacts on both ends, the SMP-FS2A-1674 mates with any standard SMP plug (male pin) connector. The straight in-line body means the signal path runs straight through — no right-angle bend, no change in orientation. The free-hanging (in-line) mounting style lets it float in a cable run or sit between two bulkhead-mounted SMP jacks without additional hardware. The PTFE dielectric provides stable phase performance across the temperature range.","metaTitle":"SMP-FS2A-1674 SMP Adapter, 50 Ohm, 40 GHz","metaDescription":"SMP-FS2A-1674 SMP to SMP adapter, 50 Ohm impedance, 40 GHz max frequency, straight plug-to-plug, female-to-female center, gold-plated beryllium copper body.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Style":"Straight","Series":"-","Package":"Bag","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Adapter Type":"Plug to Plug","Body Material":"Beryllium Copper","Center Gender":"Female to Female","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line)","Adapter Series":"SMP to SMP","Fastening Type":"Snap-On, Snap-On","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"40 GHz","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Base Product Number":"SMP-FS2A","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"SMP Plug, Female Socket","Convert From (Adapter End)":"SMP Plug, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.2200","stockQuantity":23,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4682f3a17fccdeb01a325e506a42c28b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SMP-FS2A-1674 compatible with other SMP connectors?","answer":"Yes.
