HD-BNC Adapters

Amphenol RF’s HD‑BNC adapters offer both in-series HD‑BNC (plug→jack, jack→plug, gender changers) and between-series conversions to interfaces such as BNC, SMA, 1.0‑2.3, MCX, N-Type, and HD-AFI. Available in straight barrel and tee configurations, these adapters simplify complex RF setups and protect instrumentation in test and production environments.

Constructed to high-density broadcast standards, 50 Ω HD‑BNC adapters support frequencies up to 6 GHz, while 75 Ω versions are optimized for 12G broadcast applications and capable of reaching up to 18 GHz when used with suitable cable. These adapters combine durability with precision signal performance in compact form factors.

Features and Benefits

• Dual‑Impedance Options – 50 Ω for RF/instrumentation, and 75 Ω variants optimized for 12G/18 GHz broadcast systems.
• In‑Series & Between‑Series Flexibility – Gender changers, connector savers, and adapters to BNC, SMA, MCX, N‑Type, 1.0‑2.3, HD‑AFI, and more.
• High-Density Footprint – Same bayonet feel as traditional BNC, but four times the density for space-saving rack deployment.
• Precision RF Performance – Low insertion loss (<0.1 dB) with maintained VSWR up to 6 GHz (50 Ω) or 18 GHz (75 Ω).
• Connector Saver Capability – In-series adapters extend the life of costly cable assemblies and instrument ports.

Applications

• Broadcast & UHD Video – 75 Ω variants support 12G/18 GHz transmissions for 4K/8K studios and distribution systems.
• Test & Measurement Labs – Gender changers and connector savers protect equipment in high-density rack environments.
• Telecom & Datacom – High-density interconnects for signal routing, board-to-panel, and breakout applications.
• Aerospace & Defense Instrumentation – Rugged, high-frequency adapters with elevated temperature tolerance.
