3342-1

3M's 3342-1 represents a quantum leap in D-Sub, D-Shaped Connectors - Accessories - Jackscrews technology for 5G infrastructure, offering unprecedented phase stability in mmWave antenna arrays. This precision component reduces group delay variation to <1ps across 24-40GHz bands.As a millimeter-wave optimized Jackscrew, Slotted, this solution features a dielectric constant-stabilized design that maintains <0.02dB insertion loss variation across temperature extremes. The gold-plated beryllium copper construction ensures stable contact resistance in outdoor environments.Designed specifically for D-Sub Connectors, Standard, the accessory provides >60dB port-to-port isolation for massive MIMO applications. The radome-compatible design maintains RF performance in all weather conditions.Incorporating Clip, this solution provides -55dB PIM performance while withstanding 150km/h wind loading in tower-mounted radio applications.The 0.120" (3.05mm) dimension is engineered for precise phase alignment in antenna subarrays, maintaining /20 mechanical tolerances at 28GHz.With 0.220" (5.59mm) overall length, this design accommodates integrated antenna/radio units while providing proper heat sinking for GaN power amplifiers.The 4-40 thread specification includes a corrosion-resistant coating that survives 1000 hours salt spray testing per IEC 60068-2-52, ensuring reliability in coastal base stations.
