SMA Plug (Male) to SMP Plug (Male) Adapter, DC-18GHz VSWR 1.20

SMA Plug (Male) to SMP Plug (Male) | Smooth Bore Adapter | Screw-lock | Stainless Steel Body

The ROSNOL AD-A1PS15A/1XX-1X adapter provides reliable RF performance with 50 Ω impedance and DC–18 GHz frequency range. It achieves VSWR ≤ 1.20 (≥ 20.83 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Center contact resistance is ≤ 3.0 mΩ on the SMA side, while the SMP side is designed for smooth bore engagement. Rated for 500 V rms test voltage and 250 V rms working voltage, this adapter ensures stable signal integrity. Mechanical features include screw-lock coupling on the SMA side and snap-on engagement for SMP, with mating cycles up to 500 for smooth bore and up to 1000 for limited detent configurations.

Constructed from stainless steel with passivated finish for body and coupling nut, this adapter guarantees durability and corrosion resistance. Center contacts are brass 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 15 mm [.591 in] and hex size 8 mm [.315 in].
