Both ends use a snap-on fastening, so the adapter locks into the mating plug with a positive detent — no threading or torque required. The free-hanging (in-line) mounting style makes it a straight pass-through for cable-to-cable or board-to-cable links in test setups, module interconnects, and compact RF assemblies where a rigid barrel saves space over a cable jumper. ## RF Performance and Mechanical Limits The 26.5 GHz upper frequency is the practical limit for this SMP interface.","metaTitle":"Amphenol RF SMP-FS2A-145 SMP to SMP Adapter, 50 Ohm","metaDescription":"Amphenol RF SMP-FS2A-145 straight SMP plug-to-plug adapter, female-to-female, 50 Ohm impedance, rated to 26.5 GHz.

An SMP male adapter would have male pins on one or both ends, mating with female jacks. This part is for extending or joining two male-terminated cable assemblies in-line."},{"question":"Is the SMP-FS2A-145 suitable for high-vibration environments?","answer":"The snap-on retention provides a positive detent lock, but the 100 mating cycle limit and the absence of a threaded coupling mean it is not rated for continuous high-vibration service like an SMA or TNC. It is better suited for bench interconnect, module docking, or low-vibration rack installations where the adapter is not subjected to constant mechanical shock."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/SMP-FS2A-145","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/SMP-FS2A-145 when reusing this data.
