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

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

The ROSNOL AD-K2PC25A/9X-9X is a high-performance 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, preserving signal integrity at microwave and millimeter-wave frequencies. Electrical specifications include center contact resistance ≤3 mΩ, outer contact resistance ≤2 mΩ, 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. Screw-lock coupling ensures secure engagement with recommended torque of 0.80 to 1.10 Nm, while center contact captivation ≥20 N and ≥500 mating cycles provide mechanical robustness.

Constructed from premium materials, both the 2.92mm and 3.5mm sides use beryllium copper center contacts with gold plating over non-magnetic nickel-phosphorus underplating for superior conductivity and corrosion resistance. Bodies are passivated stainless steel with PEI insulators to ensure dielectric stability, and the design supports reliable operation across −65°C to +165°C.

ROSNOL’s RF adapters deliver exceptional quality and cost efficiency, serving as a reliable alternative to leading European and American brands. All ROSNOL products 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 upon request.
