Product details
The DD78S00HE20/AA from Positronic 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-Sub, High Density architecture, the connector achieves 70% reduction in signal reflection compared to conventional designs at 28GHz frequencies.The Receptacle for Female Contacts configuration features impedance-controlled contacts that maintain <1.5:1 VSWR up to 40GHz, critical for 5G massive MIMO applications.With 78 available channels, the design supports 64T64R antenna arrays while providing separate power and control lines in single compact interface.Optimized 4 row spacing prevents mutual coupling between adjacent RF paths, maintaining >30dB isolation at 6GHz bandwidth.The 5 (DD, D) High Density 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 Cable Side, Male Jackscrew (4-40) includes integrated O-ring seals that maintain weatherproof integrity through 500 thermal cycles (-40 C to +85 C) with <1% compression set.Incorporating Backshell, Cable Clamp, Mounting Hardware, the design implements anti-walk threaded coupling that prevents loosening under vibration (10-2000Hz, 15Grms random vibration).Utilizing Steel, Clear Chromate Plated Zinc, the housing provides exceptional passive intermodulation (PIM) performance <-160dBc at 2x43dBm tones.Meeting IP65/IP67 - Dust Tight, Water Resistant, Waterproof requirements, the connector withstands wind-driven rain (60mph winds) and UV exposure per GR-487-CORE standards.
