SMA Jack (Female) to SMPM Jack (Female) Adapter, DC-18GHz VSWR1.35

SMA Jack (Female) to SMPM Jack (Female) Adapter | Screw-Lock & Snap-On | Stainless Steel Body

The ROSNOL AD-A2PM25A/9X-99 is a precision RF adapter designed for high-frequency applications requiring compact and reliable connectivity. Operating from DC to 18 GHz with a 50-ohm impedance, it achieves VSWR ≤ 1.35 and insertion loss ≤ 0.05√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, test voltage 500 V rms, and working voltage 250 V rms. Mechanical integrity is ensured through screw-lock coupling on the SMA side and snap-on engagement on the SMPM side, with axial contact captivation ≥ 28 N and ≥ 500 mating cycles for robust durability.

Constructed with stainless steel bodies for superior corrosion resistance, the adapter incorporates beryllium copper contacts plated with gold over nickel-phosphorus underplating. PTFE and PEI insulators provide excellent dielectric stability, ensuring consistent performance across a temperature range of -55°C to +165°C.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
