1.85mm Plug (Male) to 3.5mm Jack (Female) Adapter, DC-33GHz VSWR 1.15

1.85mm Plug (Male) to 3.5mm Jack (Female) Adapter | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-V1PC25A/9XX-9X is a high-performance 50-ohm straight adapter designed for DC to 33 GHz operation, achieving VSWR ≤ 1.15 (≥ 23.13 dB return loss) with insertion loss ≤ 0.05 × √F (GHz) dB. Electrical integrity is supported by insulation resistance ≥ 5 GΩ, test voltage 500 Vrms, working voltage 150 Vrms, and RF leakage ≥ 100 dB up to 1 GHz. Both ends feature screw-lock coupling for secure engagement, center-contact captivation ≥ 20 N, and mechanical durability of ≥ 500 mating cycles. Recommended torque is 0.80–1.10 Nm with defined side-specific test torque values.

Materials and plating are optimized for reliability: beryllium copper center contacts with gold plating over a non-magnetic nickel‑phosphorus underplating provide excellent conductivity and wear resistance. Stainless steel bodies and coupling nuts are passivated for corrosion protection, while PEI insulators and a silicone rubber gasket ensure stable dielectric properties and sealing. The assembly maintains performance from −55°C to +165°C.

ROSNOL’s RF adapters combine precision engineering with cost efficiency, offering a dependable alternative to major global brands. Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH, ROSNOL products ensure quality and environmental safety. Customization options for materials, plating, and mechanical design are available to support unique application needs.
