Product details
The MDMB-21P-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.With 21 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.
