Product details
The 340107702B MDMA21P-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 Plug for Male Contacts configuration features impedance-controlled contacts that maintain <1.5:1 VSWR up to 40GHz, critical for 5G massive MIMO applications.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.The 0.050 Pitch x 0.043 Row to Row incorporates waveguide-like shielding that reduces surface wave propagation by 18dB compared to standard D-Sub designs.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.Incorporating Dust Cap, the design implements anti-walk threaded coupling that prevents loosening under vibration (10-2000Hz, 15Grms random vibration).Utilizing Aluminum Alloy, Gold Plated, the housing provides exceptional passive intermodulation (PIM) performance <-160dBc at 2x43dBm tones.Precision 28µin (0.70µm) plating ensures stable contact resistance (<3m variation) despite thermal cycling and environmental exposure.
