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

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

The ROSNOL AD-K1PC25A/9XX-9X is engineered for broadband interconnects from DC to 34.5 GHz with 50 ohm impedance. It achieves a VSWR of ≤1.2 and insertion loss of ≤0.05 × √F GHz, ensuring minimal signal degradation. Electrical performance includes 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. Both sides use screw-lock coupling with recommended torque of 0.80 to 1.10 Nm; center contact captivation is ≥20 N and mechanical durability is ≥500 mating cycles.

Premium materials and plating deliver conductivity and corrosion resistance. On the 2.92mm side, the beryllium copper center contact is gold plated over non-magnetic nickel-phosphorus underplating, fit to a passivated stainless steel body and coupling nut with a PEI insulator and silicone gasket. The 3.5mm side employs the same gold-over-nickel-phosphorus stack on a beryllium copper center contact, with a passivated stainless steel body and a PEI insulator. The adapter sustains reliable operation from −55°C to +165°C.

ROSNOL’s RF adapters combine precision, consistency, and value, making them a competitive alternative to major European and American brands. All products are manufactured under ISO 9001 certified processes and fully comply with RoHS and REACH. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
