Product details
The 903-305J-51R from Amphenol RF sets the benchmark for high-frequency signal transmission in Coaxial Connectors (RF) applications. Engineered with military-grade construction, this connector delivers exceptional EMI shielding while maintaining impedance matching across {Frequency - Max} operations.Featuring SMB interface configuration, this solution provides superior VSWR performance for mission-critical RF links. When compared to industry standards, its precision-machined contacts reduce insertion loss by up to 15%.With Receptacle, Male Pin termination topology, the connector assembly ensures reliable mating cycles exceeding 500 connections. The patented contact geometry minimizes passive intermodulation (PIM) effects in dense antenna arrays.The Solder Cup system enables both field-repairable and permanent installations, offering flexibility for telecom infrastructure upgrades. Gold-plated interfaces maintain stable contact resistance below 5m .Solder technology provides 360 circumferential grounding, achieving >90dB shielding effectiveness up to {Frequency - Max}. This meets MIL-STD-348B requirements for harsh environments.Precision-tuned 50Ohm characteristics ensure minimal signal reflection in high-speed data transmission. The dielectric design compensates for velocity factor variations in {Cable Group} assemblies.Designed for Panel Mount deployment, the strain relief mechanism withstands 50N cable pull force. The anti-vibration construction maintains stable connectivity in mobile applications.The Bulkhead - Front Side Nut design facilitates blind mating in confined spaces. Precision-machined threads provide consistent torque retention between 5-7 in-lbs.The Snap-On mechanism enables tool-less installation with positive tactile engagement feedback. The self-locking design prevents accidental disconnection in high-vibration scenarios.Optimized for 4 GHz operation, the connector exhibits less than 0.2dB insertion loss at 6GHz. The broadband performance makes it ideal for software-defined radio systems.With 1 independent RF paths, the modular design supports MIMO antenna configurations. Each port features isolated shielding to prevent cross-talk.The Gold anodized finish provides corrosion resistance exceeding 500hrs salt spray testing. Color-coded variants simplify cable management in dense racks.
