This adapter is a free-hanging inline component with no panel or PCB mount — it floats in the cable run, so the installer provides strain relief on both sides. The 26.5 GHz max frequency means the adapter is characterised through the full SMP operating band; above that frequency the barrel geometry starts to resonate and insertion loss climbs. For a 100 mating-cycle life, the gold-plated BeCu centre contacts and snap-on retention are typical of SMP blind-mate interfaces — not a high-wear design, so factor in replacement for test-fixture duty where connectors are mated daily.","metaTitle":"Amphenol RF SMP-FS2A-990, SMP to SMP Adapter, 50 Ohm","metaDescription":"Amphenol RF SMP-FS2A-990 straight SMP barrel adapter, female to female, 50 Ohm impedance, rated to 26.5 GHz.
