It is a same-series (SMP to SMP) conversion adapter, meaning it joins two SMP male plugs end-to-end. The body is machined from beryllium copper with a gold finish, and the centre contacts are gold-plated beryllium copper — a material set that holds stable contact resistance across temperature swings and repeated mates. The PTFE dielectric maintains consistent impedance through the adapter body. The snap-on fastening on both ends gives a positive lock without tools.","metaTitle":"SMP-FS2A-645 SMP Adapter, 50 Ohm, 26.5 GHz, Straight","metaDescription":"SMP-FS2A-645 is a straight SMP plug-to-plug adapter, female-to-female, 50 Ohm impedance, rated to 26.5 GHz.
