554808-1

TE Connectivity AMP Connectors's 554808-1 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 Socket, 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 CHAMP Latch D-Sub Connectors, the accessory provides >60dB port-to-port isolation for massive MIMO applications. The radome-compatible design maintains RF performance in all weather conditions.The 0.320" (8.13mm) dimension is engineered for precise phase alignment in antenna subarrays, maintaining /20 mechanical tolerances at 28GHz.With 0.380" (9.65mm) overall length, this design accommodates integrated antenna/radio units while providing proper heat sinking for GaN power amplifiers.The M3.5 Socket, 6-32 Screw 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.
