1.85mm Plug (Male) to 2.92mm Plug (Male) Adapter, DC-40GHz VSWR 1.15

SMA 1.85mm Plug (Male) to 2.92mm Plug (Male) Adapter | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-V1K15A/9XX-9XX is a precision 50-ohm straight adapter engineered for broadband performance from DC to 40 GHz, delivering VSWR ≤ 1.15 (≥ 23.1 dB return loss) and ultra-low insertion loss defined as ≤ 0.05 × √F (GHz) dB. It provides insulation resistance ≥ 5 GΩ, a test voltage of 500 Vrms, working voltage of 150 Vrms, and RF leakage ≥ 100 dB up to 1 GHz, supporting clean, high-dynamic-range measurements. The adapter employs a robust screw-lock coupling on both the 1.85 mm and 2.92 mm sides, with center-contact captivation ≥ 20 N and mechanical durability rated at ≥ 500 mating cycles; recommended coupling torque is 0.80–1.10 Nm (test torque: 1.65 Nm for 1.85 mm, 1.70 Nm for 2.92 mm).

Piece-part construction features beryllium copper center contacts with 3 microinch gold plating over a non-magnetic nickel‑phosphorus underplating at 80 microinch, optimizing conductivity and wear resistance. Bodies and coupling nuts are stainless steel with passivated finish, while the insulator is PEI for stable dielectric performance. This corrosion-resistant build supports reliable operation across a −55°C to +165°C temperature range.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across RF and microwave systems at competitive pricing, making them a practical alternative to leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
