It is a same-series (SMA-to-SMA) barrel adapter, not a cross-series or gender-changing adapter. Gold-plated beryllium copper center contacts and a PTFE dielectric maintain signal integrity through the pass-through. ## Frequency Range and Impedance — What the 27 GHz and 50 Ohm Ratings Mean Rated to 27 GHz and 50 Ohms. The straight body keeps the RF path straight. ## Construction and Durability — Stainless Steel Body, 500 Mating Cycles The stainless steel body resists corrosion and mechanical wear — suited for lab benches, field test kits, and outdoor enclosures where the adapter may be repeatedly connected and disconnected. The threaded fastening (both ports) ensures a vibration-resistant connection once torqued. ## Operating Temperature Range The PTFE dielectric maintains stable dielectric constant across this range.","metaTitle":"TE 2081889-1 SMA Jack to Jack Adapter, 50 Ohm, 27 GHz","metaDescription":"TE 2081889-1 SMA female-to-female adapter, 50 Ohm impedance, rated to 27 GHz.
