2.92mm Plug (Male) to 3.5mm Plug (Male) Adapter, DC-34.5GHz VSWR1.20

2.92mm Plug (Male) to 3.5mm Plug (Male) | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-K1PC15A/9XX-9XX is a precision RF adapter operating from DC to 34.5 GHz with 50 ohm impedance. It delivers a VSWR of ≤1.2 and insertion loss of ≤0.05 × √F GHz to maintain clean return loss across high-frequency bands. Electrical ratings include insulation resistance ≥5 GΩ, test voltage 750 Vrms, working voltage 250 Vrms, RF leakage ≥100 dB up to 1 GHz, and power handling up to 22 W. The screw-lock coupling mechanism on both sides ensures secure engagement, with recommended torque of 0.80 to 1.10 Nm, center contact captivation ≥20 N, and mechanical durability ≥500 mating cycles for robust field reliability.

Materials and plating are optimized for conductivity and long-term stability. On the 2.92mm side, the center contact is beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating, mated to a passivated stainless steel body and coupling nut with a PEI insulator and silicone gasket. The 3.5mm side mirrors this gold-over-nickel-phosphorus stack on a beryllium copper center contact, with a passivated stainless steel body and coupling nut and a PEI insulator. The adapter maintains stable electrical performance from −55°C to +165°C.

ROSNOL’s precision-engineered RF adapters offer high quality at competitive pricing, serving as a dependable 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.
