SMA Jack-to-Jack Adapter, 50 Ohm, 27 GHz — Straight In-Line Pass-Through
The TE Connectivity 2081889-1 is a straight SMA jack-to-jack adapter — two female SMA ports on a single stainless steel body, converting one SMA jack to another of the same series. 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.
