Description
1.85mm Jack (Female) to 3.5mm Jack (Female) Adapter | Straight Design | Screw-Lock | Stainless Steel Body
The ROSNOL AD-V2PC25A/9X-9X is a precision 50-ohm straight adapter optimized for DC to 33 GHz, delivering VSWR ≤ 1.15 (≥ 23.13 dB return loss) and insertion loss ≤ 0.05 × √F (GHz) dB. It ensures insulation resistance ≥ 5 GΩ, test voltage 500 Vrms, working voltage 150 Vrms, and RF leakage ≥ 100 dB up to 1 GHz. Both the 1.85 mm and 3.5 mm sides utilize screw-lock coupling with center-contact captivation ≥ 20 N and mechanical endurance rated at ≥ 500 mating cycles. Recommended coupling torque is 0.80–1.10 Nm, with side-specific test torque limits supporting repeatable connections.
The adapter is constructed with beryllium copper center contacts featuring gold plating over a non-magnetic nickel‑phosphorus underplating for robust conductivity and wear resistance. Stainless steel bodies are passivated for corrosion resistance, while PEI insulators maintain dielectric stability. The design supports reliable operation across a −55°C to +165°C temperature range.
ROSNOL’s precision-engineered RF adapters deliver reliable broadband performance at competitive pricing, making them an effective alternative to leading European and American brands. All ROSNOL RF components are produced in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to accommodate specialized interconnect requirements.
