Description
2.92mm Plug (Male) to SMPM Jack (Female) | Straight Design | Screw-Lock & Snap-Lock | Stainless Steel Body
The ROSNOL AD-K1PM25A/9XX-99 is a precision RF adapter designed for ultra-high-frequency applications up to 40 GHz. It delivers a VSWR of ≤1.35 and insertion loss of ≤0.05 × √F GHz, ensuring minimal signal degradation across microwave and millimeter-wave bands. Electrical specifications include insulation resistance ≥5 GΩ, test voltage 750 Vrms, working voltage 250 Vrms, and center contact resistance ≤3.0 mΩ on the 2.92mm side and ≤6.0 mΩ on the SMPM side. RF leakage is rated at ≥100 dB up to 1 GHz. The adapter features a screw-lock mechanism on the 2.92mm side and a snap-lock coupling for SMPM, supporting multiple detent configurations for secure engagement. Mechanical durability includes ≥500 cycles for smooth bore and full detent, and ≥1000 cycles for limited detent designs.Premium materials and plating ensure superior conductivity and corrosion resistance. Both sides use beryllium copper center contacts with 3 microinch gold plating over 80 microinch non-magnetic nickel-phosphorus underplating. The 2.92mm body and coupling nut are stainless steel with passivated finish, and insulators are PEI for dielectric stability. The adapter operates reliably from −55°C to +165°C.
ROSNOL’s RF adapters deliver exceptional quality and cost efficiency, making them 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.
