Mini-BNC Connectors

Amphenol RF’s Mini‑BNC series delivers standard BNC performance in a compact package, perfect for space‑constrained designs. These connectors support frequencies up to 12 GHz—especially the 12G broadcast variants—ensuring excellent signal fidelity for high‑resolution video and precision test equipment.

Offered in straight and right‑angle PCB and cable‑mount versions, Mini‑BNC connectors are built for easy integration and long‑term reliability. Their rugged construction and fast bayonet coupling support demanding environments while maintaining superior signal quality.

Features and Benefits

• Compact form factor shrinks connector footprint while retaining full-featured BNC interface
• High-frequency support up to 12 GHz on broadcast-grade assemblies with low-loss cable
• Fast bayonet-style coupling enables quick, secure mating and unmating
• Durable build designed to withstand frequent mate/demate cycles
• Versatile configurations include cable plugs, PCB jacks, bulkheads, and right-angle versions

Key Technical Details

• Impedance: 50 Ω nominal for RF; select assemblies feature 75 Ω for 12G signal paths
• Frequency Range: DC–12 GHz on broadcast-grade low-loss coax; typical analog RF up to 4 GHz
• Mating Cycles: 500+ cycles expected, maintaining electrical and mechanical integrity
• Temperature Range: –55 °C to +105 °C depending on cable and materials
• Coupling: Bayonet (1/4‑turn) design ensures fast and reliable connections

Applications

• 12G broadcast and high-resolution video systems
• Compact instrumentation and RF test equipment
• Rack-mount RF modules and network analyzers
• Embedded RF systems needing standard BNC interface in tight spaces
• Rapid-deploy or field-test cable setups
