SMPM Jack (Female) Cable Connector for EF-047, DC-40GHz VSWR 1.40

SMPM Jack (Female) | Solder Clamp Cable Entry | Snap‑On | Beryllium Copper Body

The ROSNOL SMPM2K50‑EF047A/99 is a 50 Ω SMPM jack (female) designed for EF047‑class miniature coaxial assemblies, featuring a solder‑clamp cable entry and a plug‑in center contact for stable, low‑loss RF performance up to 40 GHz. Its snap‑on coupling mechanism enables efficient mating while maintaining VSWR ≤ 1.25 (≥ 19.08 dB return loss) from DC–26.5 GHz and ≤ 1.40 (≥ 15.56 dB) from 26.5–40 GHz. Additional electrical performance includes insulation resistance ≥ 5 GΩ, center contact resistance ≤ 6.0 mΩ, outer contact resistance ≤ 2.0 mΩ, and a working voltage rating of 325 V rms.

The connector incorporates gold‑plated beryllium copper for both the body and center contact, supported by a PTFE dielectric for stability across −65°C to +165°C. As a solder‑clamp termination type, crimp dimensions do not apply. This model is specifically suitable for EF047 cable, ensuring consistent mechanical retention and high‑frequency integrity across compact microwave interconnect designs.

ROSNOL’s precision‑engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL RF components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH requirements. Customization services for plating, materials, and mechanical design are available upon request.
