High Density Broadcast Solutions
The "High-Density Broadcast Solutions" document from Amphenol RF highlights their range of RF interconnects designed for broadcast connectivity, including BNC, Mini-BNC, 1.0/2.3 DIN, and HD-BNC connectors. These connectors offer various impedances and frequency ranges, with HD-BNC providing the highest density at an 8mm pitch and supporting data rates up to 12 Gb/s. Applications include high-definition transmission, video routing, mobile broadcast equipment, and digital signage, ensuring reliable performance and reduced equipment size without compromising signal integrity.
White Paper: High Density Interconnect Standards
The "High Density Interconnect Standards for Next Generation Broadcast Networks" paper discusses the HD-BNC connector, designed to meet modern broadcast systems' demands for higher density and performance. HD-BNC offers significant density improvements over traditional BNC connectors, with a 75 ohm interface optimized for high bandwidth up to 6 GHz. It maintains robustness and user-friendly bayonet-style mating, providing better mechanical and RF performance than other high-density alternatives like 1.0/2.3 and Mini-BNC. The HD-BNC's design ensures compatibility with industry-standard tools and cables, making it a superior choice for next-generation broadcast applications.
