It is a same-series gender-changer — you use it to extend an SMA line or reverse the gender at a bulkhead without changing the interface type. The 50 Ohm impedance matches standard 50 Ohm system impedance; the adapter is rated to 27 GHz, which covers the full SMA band through the upper end of the microwave range. The stainless steel body and PTFE dielectric give it the mechanical and electrical stability needed for repeated mate-and-demate cycles in test setups or field-installed links. ## Key RF and Mechanical Ratings The 27 GHz frequency ceiling covers the full SMA band. The 500 mating cycle rating is supported by gold-plated beryllium copper centre contacts and a stainless steel body. The body is stainless steel — passivated, not plated — so it resists corrosion. The dielectric is PTFE, which gives a stable dielectric constant across the temperature range. Centre contacts are beryllium copper with gold plating. Both ends use threaded fastening — SMA male and female threads.","metaTitle":"TE Connectivity 2081888-1 SMA Adapter, 50 Ohm, 27 GHz","metaDescription":"TE Connectivity 2081888-1 SMA plug-to-jack adapter, 50 Ohm impedance, 27 GHz max frequency, 500 mating cycles.
