RF Terminators

Amphenol RF offers a comprehensive portfolio of RF terminators engineered to electrically terminate RF ports and prevent signal reflections. By precisely matching the surge impedance of your coaxial cable, these terminators help maintain signal clarity, reduce power loss and protect sensitive system components across a wide range of frequencies and connector types.

Available in both in-series and between-series configurations, our terminators feature all industry-standard RF connector interfaces, including BNC, SMA, TNC, N‑Type, HD‑BNC, RP‑SMA, QMA, SMP, SMB, Mini‑UHF, F‑Type, 1.0/2.3 and 7‑16. These precision components are essential for test benches, broadcast equipment, telecom infrastructure and RF instrumentation.

Features and Benefits

• Full portfolio coverage — Terminators are available in all popular connector types, ensuring seamless integration with your existing RF test setups and cable assemblies.
• Signal integrity safeguarding — Precisely matched impedance minimizes reflections and helps maintain low noise and clean signal paths.
• Power and frequency versatility — Options support DC to GHz frequency ranges and power ratings suitable for typical lab, broadcast and telecom applications.
• Durable construction — Rugged designs and connector-grade materials ensure reliable mechanical and electrical performance over numerous mating cycles.
• Ease of use — Available in both plug and jack styles, with options including chains for tethered security and quick deployment.

Key Technical Details

• Impedance: 50 Ω and 75 Ω configurations to match standard RF systems.
• Frequency Range: Typical connector frequency limits apply (e.g., SMA up to ~18 GHz, BNC up to ~12 GHz with 12G broadcast cable), cable-dependent performance.
• Mating Cycles: Varies by connector series—e.g., BNC bayonet, SMA/TNC threaded, SMP/SMPM push-on; actual cycles depend on connector/cable combination.
• Power Handling: Up to ~2 W in standard terminators; N-Type terminators support higher frequency applications and moderate wattage.
• Construction: Machined housings with durable plating; select models available with chain attachments for easy deployment.

Applications

• Test & measurement: Use as dummy loads to terminate ports on network analyzers, spectrum analyzers and test fixtures.
• Broadcast & video: High-frequency BNC terminators for 12 GHz 12G‑SDI video lines prevent reflections and signal distortion.
• Telecom & wireless infrastructure: N‑Type and 7‑16 terminators used in BTS and DAS installations.
• Component evaluation: Ideal for lab characterization of amplifiers, filters and receivers.
• RF prototyping: Quick-connect options support rapid iteration and assembly flexibility.
