It's a same-series barrel adapter — no impedance transition, just a gender change — built for 50 Ohm systems from DC through 18 GHz. The stainless steel body with gold-plated finish and beryllium copper centre contacts (gold over nickel) gives it the mechanical and RF stability for repeated test-bench or field connections, rated for 500 mating cycles. PTFE dielectric keeps the insertion loss low across the band. The 50 Ohm impedance and 18 GHz max frequency define the usable RF bandwidth — this adapter will pass a clean signal from DC up to 18 GHz without a significant impedance bump at the gender transition, which is the typical failure point in a barrel adapter. The 500 mating cycle rating means the gold-over-nickel plating on the beryllium copper centre contacts will maintain low and stable contact resistance through hundreds of connect-disconnect cycles in test setups or field reconfigurations. The stainless steel body resists corrosion and galling on the threaded coupling nuts, which matters when the adapter is tightened and loosened repeatedly.","metaTitle":"1054425-1 SMA to SMA Adapter, 50 Ohm, 18 GHz, Straight","metaDescription":"1054425-1 SMA plug-to-jack adapter, 50 Ohm, DC-18 GHz, 500 mating cycles, -65°C to 125°C.
