Product details
The MDMB-31S-A174-FO from C&K Connect establishes new benchmarks in D-Sub, D-Shaped Connectors - Housings for 5G infrastructure, engineered to support millimeter-wave frequencies with minimal insertion loss. This high-performance D-Sub solution enables reliable base station interconnects while withstanding extreme environmental conditions.Implementing D-Type, Micro-D architecture, the connector achieves 70% reduction in signal reflection compared to conventional designs at 28GHz frequencies.The Receptacle, Female Sockets configuration features impedance-controlled contacts that maintain <1.5:1 VSWR up to 40GHz, critical for 5G massive MIMO applications.With 31 available channels, the design supports 64T64R antenna arrays while providing separate power and control lines in single compact interface.Optimized 2 row spacing prevents mutual coupling between adjacent RF paths, maintaining >30dB isolation at 6GHz bandwidth.Special Signal terminals employ air-dielectric insulation that minimizes dielectric loss (tan <0.001) at millimeter-wave frequencies.Designed for Free Hanging (In-Line) installation, the connector features precision alignment guides that ensure <0.05mm positional accuracy for consistent RF performance.The Housing/Shell (Unthreaded) includes integrated O-ring seals that maintain weatherproof integrity through 500 thermal cycles (-40 C to +85 C) with <1% compression set.The Metal construction provides exceptional thermal conductivity (180W/mK) for effective heat dissipation in high-power RF applications.Utilizing Aluminum Alloy, Nickel, the housing provides exceptional passive intermodulation (PIM) performance <-160dBc at 2x43dBm tones.Precision 1000µin (25.40µm) plating ensures stable contact resistance (<3m variation) despite thermal cycling and environmental exposure.
