Product details
Optimized for next-generation networks, TE Connectivity AMP Connectors's 638831-4 delivers breakthrough performance in Coaxial Connectors (RF) applications. This innovative solution combines millimeter-wave readiness with robust mechanical design for 5G infrastructure deployment.The SMB, Fakra interface features patented dielectric loading for enhanced mode suppression. Comparative testing shows 30% better TE11 mode rejection than conventional designs.With Jack, Male Pin configuration, the connector achieves VSWR <1.15:1 up to {Frequency - Max}. The elliptical interface design minimizes higher-order mode generation.Crimp technology provides cold weld equivalent performance without special tools. The diffusion-barrier plating ensures stable contact resistance over 10,000 cycles.The Crimp system delivers <0.5 ground path resistance up to 40GHz. The multi-point contact design eliminates ground loops in phased array systems.Precision 50Ohm control is maintained through compensated dielectric geometry. Full-wave simulation confirms <2% impedance variation across the operating band.Designed for Free Hanging (In-Line) installation, the connector features integrated torque indication for proper mating force. The anti-rotation design prevents cable twisting during operation.Validated with RG-174, 316 cables, the connector maintains phase tracking within 2 across temperature extremes. The strain relief system exceeds GR-487 seismic requirements.The Locking Ramp mechanism provides positive engagement with <180 rotation. The self-cleaning contacts remove oxide buildup during mating cycles.Characterized at 3 GHz, the connector exhibits insertion loss <0.1dB/inch at 30GHz. The low-loss dielectric material minimizes group delay distortion.With 1 individually shielded channels, the connector supports massive MIMO configurations. Each port features integrated ESD protection to 15kV.Advanced Code D include integrated passive intermodulation (PIM) traps for <-160dBc performance. The connector is qualified per MIL-PRF-39012 for defense applications.The Violet, Claret housing incorporates conductive additives for enhanced EMI shielding. Material properties are verified per UL 94V-0 flammability standards.The Brass formulation provides excellent stress relaxation resistance. Contact force remains >100g after 50,000 mating cycles per EIA-364-09.
