SMA Plug (Male) to SSMA Jack (Female) Adapter, DC-18GHz VSWR 1.20

SMA Plug (Male) to SSMA Jack (Female) | Straight Adapter | Screw-lock | Stainless Steel Body

The ROSNOL AD-A1SA25A/9XX-9X adapter delivers high-performance RF connectivity with 50 Ω impedance and DC–18 GHz frequency range. It achieves VSWR ≤ 1.20 (≥ 20 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Contact resistance is ≤ 3.0 mΩ for both SMA and SSMA sides, while outer contact resistance is ≤ 3.0 mΩ. Rated for 1000 V rms test voltage and 480 V rms working voltage, it supports RF leakage ≥ 100 dB up to 1 GHz and power handling up to 200 W at 2 GHz. Mechanical integrity includes screw-lock coupling, axial captivation ≥ 28 N, torque range 0.9 Nm, and minimum 500 mating cycles.

Constructed from stainless steel with passivated finish for body and coupling nut, this adapter guarantees durability and corrosion resistance. Center contacts are beryllium copper with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. Insulators are PTFE for both ends, complemented by silicone rubber gaskets for environmental sealing. Dimensions include overall length 20.58 mm [.810 in], hex sizes 8 mm [.315 in] and 7 mm [.276 in], and thread No.10-36 UNS-2A.
